5 Hardkey/Softkey Reference 5-1
Hardkey/Softkey Reference Key Reference Key Reference This chapter contains information on the following topics: • softkey and front-panel functions in alphabetical order (includes a brief description of each function) • cross reference of programming commands to key functions • cross reference of softkeys to front-panel access keys NOTE 5-2 The SERVICE MENU keys are not included in this chapter. Information on the SERVICE MENU keys can be found in the service guide.
Hardkey/Softkey Reference Where to Look for More Information Where to Look for More Information Additional information about many of the topics discussed in this chapter is located in the following areas: • "Making Measurements" in the user’s guide contains step-by-step procedures for making measurements or using particular functions.
Hardkey/Softkey Reference Analyzer Functions Analyzer Functions This section contains an alphabetical listing of softkey and front-panel functions, and a brief description of each function. . is used to add a decimal point to the number you are entering. − is used to add a minus sign to the number you are entering. is used to step up the current value of the active function. The analyzer defines the step size for different functions. No units terminator is required.
Hardkey/Softkey Reference Analyzer Functions ∆ MODE MENU goes to the delta marker menu, which is used to read the difference in values between the active marker and a reference marker. ∆ MODE OFF turns off the delta marker mode, so that the values displayed for the active marker are absolute values. ∆ REF = 1 establishes marker 1 as a reference. The active marker stimulus and response values are then shown relative to this delta reference.
Hardkey/Softkey Reference Analyzer Functions 2.92* 85056K selects the 85056K cal kit. 2.92mm other kits selects the 2.92 mm cal kit model. 3.5mmC 85033C selects the 85033C cal kit. 3.5mmD 85052 selects the 85052B or the 85052D cal kit. 3.5mmE 85033D/E selects the 85033D or the 85033E cal kit. 4X: [1] [2]/[3] [4] sets up a four-graticule display with channel 2 in the upper right quadrant and channel 3 in the lower left quadrant.
Hardkey/Softkey Reference Analyzer Functions ADD 1) displays the edit segment menu and adds a new segment to the end of the list. The new segment is initially a duplicate of the segment indicated by the pointer > and selected with the SEGMENT softkey. 2) adds a new frequency band to the Ripple Limit list which is indicated by the pointer >. The new frequency band is a duplicate of the most recently selected frequency band. ADDRESS: 8720 sets the GPIB address of the analyzer, using the entry controls.
Hardkey/Softkey Reference Analyzer Functions ARBITRARY IMPEDANCE defines the standard type to be a load, but with an arbitrary impedance (different from system Z0). ASSERT SRQ sets the sequence bit in the Event Status Register, which can be used to generate a SRQ (service request) to the system controller. AUTO FEED ON off turns the plotter auto feed function on or off when in the define plot menu. It turns the printer auto feed on or off when in the define print menu.
Hardkey/Softkey Reference Analyzer Functions AVERAGING RESTART averaging starts at 1 and averages each new sweep into the trace until it reaches the specified averaging factor. The sweep count is displayed in the status notations area below “Avg” and updated every sweep as it increments. Avg is used to access three different noise reduction techniques: sweep-to-sweep averaging, display smoothing, and variable IF bandwidth. Any or all of these can be used simultaneously.
Hardkey/Softkey Reference Analyzer Functions BRIGHTNESS adjusts the brightness of the color being modified. Refer to the section on adjusting the display color in the “Using Measurement Functions” chapter of the user’s guide for an explanation of using this softkey for color modification of display attributes. BW DISPLAY on OFF displays the measured bandwidth value to the right of the pass/fail message. BW MARKER on OFF displays the cutoff frequencies of the bandwidth using markers on the data trace.
Hardkey/Softkey Reference Analyzer Functions Cal key leads to a series of menus to perform measurement calibrations for vector error correction (accuracy enhancement), and for specifying the calibration standards used. The CAL key also leads to softkeys which activate interpolated error correction and power meter calibration. CAL FACTOR accepts a power sensor calibration factor % for the segment.
Hardkey/Softkey Reference Analyzer Functions — N 50Ω 85054 — N 75Ω 85036 — TRL 3.5mm 85052C CAL Z0: LINE Z0 this default selection establishes the TRL/LRM LINE/MATCH standard as the characteristic impedance. CAL Z0: SYSTEM Z0 allows you to modify the characteristic impedance of the system for TRL/LRM calibration. CALIBRATE MENU leads to the calibration menu, which provides several accuracy enhancement procedures ranging from a simple frequency response calibration to a full two-port calibration.
Hardkey/Softkey Reference Analyzer Functions CH3 DATA LIMIT LN selects channel 3 data trace and limit line for display color modification. CH3 MEM selects channel 3 memory trace for display color. CH3 MEM [ ] brings up the printer color selection menu. The channel 2 data trace default color is green for color prints. CH4 DATA [ ] brings up the printer color selection menu. The channel 4 data trace default color is blue for color prints.
Hardkey/Softkey Reference Analyzer Functions CHANNEL POSITION configures multiple-channel displays so that the auxiliary channels are adjacent to or beneath the primary channels. CHOP A and B measures A and B inputs simultaneously for faster measurements. CLEAR BIT when the parallel port is configured for GPIO, 8 output bits can be controlled with this key. When this key is pressed, “TTL OUT BIT NUMBER” becomes the active function.
Hardkey/Softkey Reference Analyzer Functions CONTINUE ECal is displayed during ECal dual module operation and during manual thru operation as a pause in the process of measurement. After you have inserted the next module or connected the thru, press this softkey to continue the process. CONTINUE SEQUENCE resumes a paused sequence.
Hardkey/Softkey Reference Analyzer Functions D2/D1 to D2 on OFF this math function ratios channels 1 and 2, and puts the results in the channel 2 data array. Both channels must be on and have the same number of points. Refer to the "Making Measurements" chapter in the user’s guide for information on how to use this function to make gain compression measurements. DAC NUM HIGH BAND sets the source tune DAC for frequencies above 20.05 GHz.
Hardkey/Softkey Reference Analyzer Functions DEFAULT PLOT SETUP resets the plotting parameters to their default values. DEFAULT PRNT SETUP resets the printing parameters to their default values. DEFINE DISK-SAVE leads to the define save menu. Use this menu to specify the data to be stored on disk in addition to the instrument state. DEFINE PLOT leads to a sequence of three menus. The first defines which elements are to be plotted and the auto feed state.
Hardkey/Softkey Reference Analyzer Functions DIRECTORY SIZE lets you specify the number of directory files to be initialized on a disk. This is particularly useful with a hard disk, where you may want a directory larger than the default 256 files, or with a floppy disk you may want to reduce the directory to allow extra space for data files. The number of directory files must be a multiple of 8. The minimum number is 8, and there is no practical maximum limit.
Hardkey/Softkey Reference Analyzer Functions DO SEQUENCE jumps to a softkey position, not to a specific sequence title. Whatever sequence is in the selected softkey position will run when the DO SEQUENCE command is executed. This command prompts the operator to select a destination sequence position. DONE 1-PORT CAL finishes one-port calibration (after all standards are measured) and turns error correction on.
Hardkey/Softkey Reference Analyzer Functions EACH SWEEP Power meter calibration occurs on each sweep. Each measurement point is measured by the power meter, which provides the analyzer with the actual power reading. The analyzer corrects the power level at that point. The number of measurement/correction iterations performed on each point is determined by the NUMBER OF READINGS softkey. This measurement mode sweeps slowly, especially when the measured power is low.
Hardkey/Softkey Reference Analyzer Functions END SWEEP HIGH PULSE sets the TTL output on TEST SEQ BNC or the test set interconnect to normally high with a 10 microseconds pulse high at the end of each sweep. END SWEEP LOW PULSE sets the TTL output on TEST SEQ BNC or the test set interconnect to normally low with a 10 µs pulse low at the end of each sweep. ENHANCED RESPONSE provides access to the series of menus used to perform an enhanced response calibration. ENH. REFL.
Hardkey/Softkey Reference Analyzer Functions EXTENSION INPUT B adds electrical delay to the input B reference plane for any B input measurements including S-parameters. EXTENSION PORT 1 extends the reference plane for measurements of S11, S21, and S12. EXTENSION PORT 2 extends the reference plane for measurements of S22, S12, and S21. EXTENSIONS on OFF toggles the reference plane extension mode.
Hardkey/Softkey Reference Analyzer Functions FIXED MKR STIMULUS changes the stimulus value of the fixed marker. Fixed marker stimulus values can be different for the two channels if the channel markers are uncoupled using the marker mode menu. To read absolute active marker stimulus values following a MKR ZERO operation, the stimulus value can be reset to zero. FIXED MKR VALUE changes the response value of the fixed marker. In a Cartesian format this is the y-axis value.
Hardkey/Softkey Reference Analyzer Functions FORMAT INT MEMORY clears all internal save registers and associated cal data and memory traces. FORMAT: LIF causes subsequent disk initialization to use the LIF disk format. FORMAT: LIF is the default setting. FORWARD: OPENS provides access to the menu for selecting an open calibration type when the cal kit defines more than one open standard. FREQ OFFS MENU leads to the frequency offset menu (Option 089 only).
Hardkey/Softkey Reference Analyzer Functions G+jB MKR G/n displays the complex admittance values of the active marker in rectangular form. The active marker values are displayed in terms of conductance (in Siemens), susceptance, and equivalent capacitance or inductance. Siemens are the international units of admittance, and are equivalent to mhos (the inverse of Ωs). The Smith chart graticule is changed to admittance form. giga/nano (109 / 10−9). Used to terminate numeric entries.
Hardkey/Softkey Reference Analyzer Functions GRAPH FMT [ ] sets the format of the graphic file when FILETYPE: GRAPHIC is selected. The only graphic selection currently available is the JPEG format. GRAPHICS on OFF specifies whether or not to store display graphics on disk with the instrument state. GRATICULE [ ] brings up the graticule print color definition menu. The graticule default print color is cyan. GRATICULE selects the display graticule for color modification.
Hardkey/Softkey Reference Analyzer Functions IF LOOP < > COUNTER 0 prompts the user to select a destination sequence position (SEQUENCE 1 through 6). When the value of the loop counter is no longer zero, the sequence in the specified position will run. IMAGINARY displays only the imaginary (reactive) portion of the measured data on a Cartesian format. This format is similar to the real format except that reactance data is displayed on the trace instead of impedance data.
Hardkey/Softkey Reference Analyzer Functions KIT DONE (MODIFIED) terminates the cal kit modification process, after all standards are defined and all classes are specified. Be sure to save the kit with the SAVE USER KIT softkey, if it is to be used later. LABEL CLASS leads to the label class menu, to give the class a meaningful label for future reference during calibration. LABEL CLASS DONE finishes the label class function and returns to the modify cal kit menu.
Hardkey/Softkey Reference Analyzer Functions LIMIT TEST on OFF turns limit testing on or off. When limit testing is on, the data is compared with the defined limits at each measured point. Limit tests occur at the end of each sweep, whenever the data is updated, when formatted data is changed, and when limit testing is first turned on. Limit testing is available for both magnitude and phase values in Cartesian formats.
Hardkey/Softkey Reference Analyzer Functions LIST provides a tabular listing of all the measured data points and their current values, together with limit information if it is turned on. At the same time, the screen menu is presented, to enable hard copy listings and access new pages of the table. 30 lines of data are listed on each page, and the number of pages is determined by the number of measurement points specified in the stimulus menu.
Hardkey/Softkey Reference Analyzer Functions LO MENU leads to the LO menu. Allows you to configure the external source for frequency offset. LO SOURCE ADDRESS shows the GPIB address of the LO source. LOAD defines the standard type as a load (termination). Loads are assigned a terminal impedance equal to the system characteristic impedance Z0, but delay and loss offsets may still be added. If the load impedance is not Z0, use the arbitrary impedance standard definition.
Hardkey/Softkey Reference Analyzer Functions LOOP COUNTER displays the current value of the loop counter and allows you to change the value of the loop counter. Enter any number from 0 to 32767 and terminate with the x1 key. The default value of the counter is zero. This command should be placed in a sequence that is separate from the measurement sequence. For this reason: the measurement sequence containing a loop decision command must call itself in order to function.
Hardkey/Softkey Reference Analyzer Functions MAN ’ L THRU on OFF allows the insertion of a different thru during the ECal correction routine. When turned ON, the routine will pause for the insertion of the thru and display a menu that contains a continue and abort softkey. MANUAL TRG ON POINT waits for a manual trigger for each point. Subsequent pressing of this softkey triggers each measurement.
Hardkey/Softkey Reference Analyzer Functions MARKER → DELAY adjusts the electrical delay to balance the phase of the DUT. This is performed automatically, regardless of the format and the measurement being made. Enough line length is added to or subtracted from the receiver input to compensate for the phase slope at the active marker position. This effectively flattens the phase trace around the active marker, and can be used to measure electrical length or deviation from linear phase.
Hardkey/Softkey Reference Analyzer Functions MARKER 2 turns on marker 2 and makes it the active marker. If another marker is present, that marker becomes inactive and is represented on the display as ∆. MARKER 3 turns on marker 3 and makes it the active marker. MARKER 4 turns on marker 4 and makes it the active marker. MARKER 5 turns on marker 5 and makes it the active marker.
Hardkey/Softkey Reference Analyzer Functions MAXIMUM FREQUENCY is used to: 1) define the highest frequency at which a calibration kit standard can be used during measurement calibration. In waveguide, this is normally the upper cutoff frequency of the standard. or 2) set the maximum frequency of the selected frequency band when setting up ripple test parameters. MAXIMUM RIPPLE sets the maximum ripple allowed of the selected frequency band. The maximum allowable ripple is 100 dB.
Hardkey/Softkey Reference Analyzer Functions MINIMUM FREQUENCY is used to: 1) define the lowest frequency at which a calibration kit standard can be used during measurement calibration. In waveguide, this must be the lower cutoff frequency of the standard, so that the analyzer can calculate dispersive effects correctly (see OFFSET DELAY ). or 2) set the minimum frequency of the selected frequency band when setting up ripple test parameters.
Hardkey/Softkey Reference Analyzer Functions MODULE A b selects the module to be used in the ECal operation. Select the module according to frequency range and connector type of the DUT. In some cases the Module B selection will not be used. MODULE INFO presents a text window that contains information about the selected module. MORE RANGES provides access to more power ranges. (ES only) N 50Ω 85054 selects the 85054 cal kit. N 50Ω 85032F selects the 85032F cal kit.
Hardkey/Softkey Reference Analyzer Functions The possible values that can be entered for number of points are 3, 11, 26, 51, 101, 201, 401,801, and 1601. The number of points can be different for the two channels if the stimulus values are uncoupled. In list frequency sweep, the number of points displayed is the total number of frequency points for the defined list (see “Sweep Types” in the “Operating Concepts” chapter of the user’s guide).
Hardkey/Softkey Reference Analyzer Functions ONE-PATH 2-PORT leads to the series of menus used to perform a high-accuracy two-port calibration without an S-parameter test set. This calibration procedure effectively removes directivity, source match, load match, isolation, reflection tracking, and transmission tracking errors in one direction only. Isolation correction can be omitted for measurements of devices with limited dynamic range.
Hardkey/Softkey Reference Analyzer Functions PARALL IN IF BIT L while creating a sequence, this softkey inserts a command to jump to another sequence if the single input selected is in a low state. PARALLEL sets the printer or plotter port to parallel. PARALLEL [COPY/GPIO] toggles the parallel output port between the copy and GPIO output modes. PARALLEL OUT ALL allows you to input a number (0 to 255) in base 10, and outputs it to the bus as binary, when the parallel port is in GPIO mode.
Hardkey/Softkey Reference Analyzer Functions PHASE OFFSET adds or subtracts a phase offset that is constant with frequency (rather than linear). This is independent of MARKER → DELAY and ELECTRICAL DELAY . PHASE (Option 010 only) displays a Cartesian format of the phase portion of the data, measured in degrees. This format displays the phase shift versus frequency.
Hardkey/Softkey Reference Analyzer Functions PLTR PORT SERIAL configures the analyzer for a plotter that has a serial (RS-232) interface. PLTR TYPE [PLOTTER] selects a pen plotter such as the HP 7440A, HP 7470A, HP 7475A, or HP 7550B as the plotter type. PLTR TYPE [HPGL PRT] selects a PCL5 compatible printer, which supports HP-GL/2, such as the LaserJet III or LaserJet 4 for a monochrome plotter type, or the DeskJet 1200C for a color plotter type. POLAR displays a polar format.
Hardkey/Softkey Reference Analyzer Functions This feature may be used to compensate for attenuation non-linearities in either a directional coupler or a power splitter. Up to 12 segments may be entered, each with a different frequency and power loss value. POWER MTR toggles between 436A or 438A/437 . These power meters are GPIB compatible with the analyzer. The model number in the softkey label must match the power meter to be used.
Hardkey/Softkey Reference Analyzer Functions PRINT ALL MONOCHROME when displaying list values, prints the entire list in monochrome. When displaying operating parameters, prints all but the last page in monochrome. The data is sent to the printer as ASCII text rather than as raster graphics, which causes the printout to be faster. PRINT: COLOR sets the print command to default to a color printer. The printer output is always in the analyzer default color values.
Hardkey/Softkey Reference Analyzer Functions PWR LOSS on OFF turns on or off power loss correction. Power loss correction should be used when the power output is measured by a directional coupler. Enter the power loss caused by the coupled arm with the LOSS/SENSR LISTS softkey submenus described below. PWR RANGE AUTO man toggles the power range mode between auto and manual. Auto mode selects the power range based on the power selected.
Hardkey/Softkey Reference Analyzer Functions RAW OFFSET On Off selects whether sampler and attenuator offsets are ON or OFF. By selecting raw offsets OFF, a full two port error correction can be performed without including the effects of the offsets. It also saves substantial time at recalls and during frequency changes. Raw offsets follow the channel coupling. This softkey is used with "Take4" mode. Refer to the examples in the programmer’s guide.
Hardkey/Softkey Reference Analyzer Functions RECALL COLORS recalls the previously saved modified version of the color set. This key appears only when a color set has been saved. RECALL KEYS accesses two recall keys which allows you to set the recall keys menu as the initial menu displayed when Save/Recall is pressed or select specific registers to recall. RECALL KEYS MENU provides access to the recall keys menu where specific registers can be recalled.
Hardkey/Softkey Reference Analyzer Functions REFL: REV S22 (B/R) defines the measurement as S22, the complex reflection coefficient (magnitude and phase) of the test device output. REFLECT AND LINE measures the reflection and thru paths of the current calibration standard. REFLECTION leads to the reflection calibration menu. REFLECTION 1-PORT leads to the reflection calibration menu (ET only). In the ECal menu, this softkey performs the reflection 1-port calibration.
Hardkey/Softkey Reference Analyzer Functions • When in the response and isolation menu, RESPONSE ISOL'N leads to the menus used to perform a response and isolation measurement calibration, for measurement of devices with wide dynamic range. This procedure effectively removes the same frequency response errors as the response calibration. In addition, it effectively removes the isolation (crosstalk) error in transmission measurements or the directivity error in reflection measurements.
Hardkey/Softkey Reference Analyzer Functions REV TRANS THRU is used to enter the standard numbers for the reverse transmission (thru) calibration. (For default kits, this is the thru.) REVERSE: OPENS provides access to the menu for selecting an open calibration type when the cal kit defines more than one open standard. RF > LO adjusts the source frequency higher than the LO by the amount of the LO (within the limits of the analyzer).
Hardkey/Softkey Reference Analyzer Functions RIPL VALUE [ ] displays the ripple value of the selected frequency band. The ripple value can be displayed in two ways or turned off. Selecting OFF removes the displayed ripple value from the display. Selecting ABSOLUTE or MARGIN displays the ripple value. The ripple value is preceded on the display by an indicator of the selected band. For example, when the ripple value is preceded by “B2”, this indicates that the ripple value shown is for Band 2.
Hardkey/Softkey Reference Analyzer Functions S11B is used to enter the standard numbers for the second class required for an S11 1-port calibration. (For default cal kits, this is the short.) S11C is used to enter the standard numbers for the third class required for an S11 1-port calibration. (For default kits, this is the load.) S11 REFL SHORT measures the short circuit TRL/LRM calibration data for PORT 1. S11/S21 ENH. RESP.
Hardkey/Softkey Reference Analyzer Functions SAVE USER KIT stores the user-modified or user-defined kit into memory, after it has been modified. SAVE USING ASCII selects ASCII format for data storage to disk. SAVE USING BINARY selects binary format for data storage. Save/Recall provides access to all the menus used for saving and recalling instrument states in internal memory and for storing to, or loading from the internal or external disk.
Hardkey/Softkey Reference Analyzer Functions SEARCH: OFF turns off the marker search function. SEARCH: TARGET searches for the user-specified target point on the trace. SEGMENT specifies which limit segment in the table is to be modified. A maximum of three sets of segment values are displayed at one time, and the list can be scrolled up or down to show other segment entries. Use the entry block controls to move the pointer > to the required segment number.
Hardkey/Softkey Reference Analyzer Functions SELF DIAGNOSE prompts the analyzer to run a series of tests to determine a problem. Seq accesses a series of sequencing menus. These allow you to create, modify, and store up to 6 sequences which can be run automatically. SEQUENCE 1 SEQ1 activates editing mode for the segment titled "SEQ1" (default title). SEQUENCE 2 SEQ2 activates editing mode for the segment titled "SEQ2" (default title).
Hardkey/Softkey Reference Analyzer Functions SET MONTH allows you to set the month in the analyzer's internal clock. SET REF: REFLECT sets the measurement reference plane to the TRL/LRM REFLECT standard. SET REF: THRU sets the measurement reference plane to the TRL/LRM THRU standard. SET YEAR allows you to set the year in the analyzer's internal clock. SET Z0 sets the characteristic impedance used by the analyzer in calculating measured impedance with Smith chart markers and conversion parameters.
Hardkey/Softkey Reference Analyzer Functions SINGLE POINT sets the limits at a single stimulus point. If limit lines are on, the upper limit value of a single point limit is displayed as ∨ and the lower limit is displayed as ∧. A limit test at a single point not terminating a flat or sloped line tests the nearest actual measured data point. A single point limit can be used as a termination for a flat line or sloping line limit segment.
Hardkey/Softkey Reference Analyzer Functions SMOOTHING APERTURE lets you change the value of the smoothing aperture as a percent of the span. When smoothing aperture is the active function, its value in stimulus units is displayed below its percent value in the active entry area. Smoothing aperture is also used to set the aperture for group delay measurements. Note that the displayed smoothing aperture is not the group delay aperture unless smoothing is on.
Hardkey/Softkey Reference Analyzer Functions SPUR AVOID On Off selects whether spur avoidance is ON or OFF. Selecting spur avoidance OFF, along with selecting raw offsets OFF, saves substantial time at recalls and during frequency changes. Spur avoidance is always coupled between channels. STANDARD DONE returns to the define standard menu. Start is used to define the start frequency of a frequency range. When the Start key is pressed it becomes the active function.
Hardkey/Softkey Reference Analyzer Functions STIMULUS VALUE sets the starting stimulus value of a segment, using entry block controls. The ending stimulus value of the segment is defined by the start of the next line segment. No more than one segment can be defined over the same stimulus range. STIMULUS OFFSET adds or subtracts an offset in stimulus value. This allows limits already defined to be used for testing in a different stimulus range. Use the entry block controls to specify the offset required.
Hardkey/Softkey Reference Analyzer Functions The system controller mode can be used without knowledge of GPIB programming. However, the GPIB address must be entered for each peripheral device. This mode can only be selected manually from the analyzer's front panel, and can be used only if no active computer controller is connected to the system through GPIB. If you try to set system controller mode when another controller is present, the message ANOTHER SYSTEM CONTROLLER ON GPIB is displayed.
Hardkey/Softkey Reference Analyzer Functions TERMINAL IMPEDANCE is used to specify the (arbitrary) impedance of the standard, in Ωs. TEST OPTIONS is used to set configurations before running the service tests. TESTPORT 1 2 is used to direct the RF power to port 1 or port 2. (For non-S parameter inputs only.) TESTSET I/O FWD is used to support specialized test sets, such as a test set that measures duplexers.
Hardkey/Softkey Reference Analyzer Functions TITLE presents the title menu in the softkey labels area and the character set in the active entry area. These are used to label the active channel display. A title more menu allows up to four values to be included in the printed title active entry, active marker amplitude, limit test results, and loop counter value. TITLE SEQUENCE allows the operator to rename any sequence with an eight character title.
Hardkey/Softkey Reference Analyzer Functions TITLE TO PRNTR/GPIB outputs a title string to any device with an GPIB address that matches the address set with the analyzer Local SET ADDRESSES ADDRESS: PRINTER commands. This softkey is generally used for two purposes: • Sending a title to a printer for data logging or documentation purposes. • Sending commands to a printer or other GPIB device. TRACE TYPE [DATA] is located in the ECal confidence menu and ECal service menu.
Hardkey/Softkey Reference Analyzer Functions TRANSMISSION leads to the transmission menu. TRIGGER MENU presents the trigger menu, which is used to select the type and number of the sweep trigger. TRIGGER: TRIG OFF turns off external trigger mode. TRL 3.5 mm 85052C selects the 85052C cal kit. TRL*/LRM* 2-PORT leads to the TRL*/LRM* 2-port calibration menu. TRL/LRM OPTION selects the TRL/LRM Option Menu, under the modify cal kit menu.
Hardkey/Softkey Reference Analyzer Functions USE MEMORY ON off (Option 010 only) remembers a specified window pulse width (or step rise time) different from the standard window values. A window is activated only for viewing a time domain response, and does not affect a displayed frequency domain response.
Hardkey/Softkey Reference Analyzer Functions VOLUME NUMBER specifies the number of the disk volume to be accessed. In general, all 3.5 inch floppy disks are considered one volume (volume 0). For hard disk drives, such as the HP 9153A (Winchester), a switch in the disk drive must be set to define the number of volumes on the disk. WAIT x pauses the execution of subsequent sequence commands for x number of seconds. Terminate this command with x1 .
Hardkey/Softkey Reference Analyzer Functions If a delta marker or fixed marker is on, it is used as the reference point from which the bandwidth amplitude is measured. For example, if marker 1 is the delta marker and is set at the passband maximum, and the width value is set to −3 dB, the bandwidth search finds the bandwidth cutoff points 3 dB below the maximum and calculates the 3 dB bandwidth and Q.

Preset State and Memory Allocation Preset State Preset State When the Preset key is pressed, the analyzer reverts to a known state called the factory preset state. This state is defined in Table 8-1. There are subtle differences between the preset state and the power-up state. These differences are documented in Table 8-3. If power to non-volatile memory is lost, the analyzer will have certain parameters set to default settings. The affected parameters are shown in Table 8-4.

Preset State and Memory Allocation Memory Allocation Memory Allocation The analyzer is capable of saving complete instrument states for later retrieval. It can store these instrument states into the internal memory, to the internal disk, or to an external disk.
Preset State and Memory Allocation Memory Allocation NOTE Even though calibration data is stored in non-volatile memory, if the associated instrument state is not saved, you will not be able to retrieve the calibration data after a power cycle.
Preset State and Memory Allocation Memory Allocation Determining Memory Requirements Table 8-5 shows the memory requirements of calibration arrays and memory trace arrays to help you approximate memory requirements. For example, add the following memory requirements: • a full 2-port calibration with 801 points (58 k) • the memory trace array (4.9 k) • the instrument state (6 k) The total memory requirement is 68.9 kbytes. There is sufficient memory to store 29 calibrations of this type.

Preset State and Memory Allocation Memory Allocation Storing Data to Disk You can use the internal disk drive or connect an external disk drive for storage of instrument states, calibration data, measurement data, and plot files. (Refer to the “Printing, Plotting, and Saving Measurement Results” chapter in the user’s guide for more information on saving measurement data and plot files.) The analyzer displays one file name per stored instrument state when you list the disk directory.

Preset State and Memory Allocation Memory Allocation If correction is on at the time of an external store, the calibration set is stored to disk. (Note that inactive calibrations are not stored to disk.) When an instrument state is loaded into the analyzer from disk, the stimulus and response parameters are restored first. If correction is on for the loaded state, the analyzer will load a calibration set from disk that carries the same title as the one stored for the instrument state.

Understanding the CITIfile Data Format Using This Chapter Using This Chapter The descriptions and examples shown in this chapter demonstrate how CITIfile may be used to store and transfer both measurement information and data. The use of a single, common format will allow data to be more easily moved between instruments and computers.
Understanding the CITIfile Data Format The CITIfile Data Format The CITIfile Data Format Description and Overview CITIfile is a standardized data format, used for exchanging data between different computers and instruments. CITIfile is an abbreviation for “Common Instrumentation Transfer and Interchange file”. This standard has been a group effort between instrument designers and designers of computer-aided design programs.
Understanding the CITIfile Data Format The CITIfile Data Format A CITIfile Package A typical package is divided into two parts: The first part, the header, is made up of keywords and setup information. The second part, the data, usually consists of one or more arrays of data. Example 1 shows the basic structure of a CITIfile package: Example 1, A CITIfile Package The “header” part CITIFILE A.01.00 NAME MEMORY VAR FREQ MAG 3 DATA S RI The “data” part BEGIN -3.54545E-2, -1.38601E-3 0.23491E-3, -1.
Understanding the CITIfile Data Format The CITIfile Data Format A CITIfile package may contain more than one array of data. Arrays of data start after the BEGIN keyword, and the END keyword will follow the last data element in an array. A CITIfile package does not necessarily need to include data arrays; for instance, CITIfile could be used to store the current state of an instrument. In that case the keywords VAR, DATA, BEGIN, and END would not be required.

Understanding the CITIfile Data Format CITIfile Keywords CITIfile Keywords Keyword Explanation and Examples CITIFILE CITIFILE A.01.01 identifies the file as a CITIfile, and indicates the revision level of the file. The CITIfile keyword and revision code must precede any other keywords. The CITIfile keyword at the beginning of the package assures the device reading the file that the data that follows is in the CITIfile format. The revision number allows for future extensions of the CITIfile standard.
Understanding the CITIfile Data Format CITIfile Keywords SEG_LIST_BEGIN SEG_LIST_BEGIN indicates that a list of segments for the independent variable follow. Format for the segments is: [segment type] [start] [stop] [number of points]. The current implementation only supports a single segment. If there is more than one segment, the VAR_LIST_BEGIN construct is used. CITIfile revision A.01.00 supports only the SEG (linear segment) segment type.
Understanding the CITIfile Data Format CITIfile Keywords CONSTANT CONSTANT [name] [value] allows for the recording of values which don’t change when the independent variable changes. CONSTANTs are part of the main CITIfile definition. Users must not define their own CONSTANTs. Use the #KEYWORD device specification to create your own KEYWORD instead. The #NA device specification is an example of this. No constants were defined for revision A.01.00 of CITIfile. CITIfile revision A.01.
Understanding the CITIfile Data Format Useful Calculations Useful Calculations This section contains information on computing frequency points and expressing CITIfile data in other data formats. Computing Frequency Points In CITIfile, the frequency data is not listed point by point, only the start and stop values are given. If you are using a spreadsheet program, you can create a new frequency column to the left of the data pairs.
Understanding the CITIfile Data Format Useful Calculations Expressing CITIfile Data in Other Data Formats CITIfile data is represented in real and imaginary pairs. Equations can be used to express this information in logarithmic magnitude, phase, polar, and Smith chart formats. Refer to the following table for these equations.

10 Determining System Measurement Uncertainties 10-1
Determining System Measurement Uncertainties Introduction Introduction In any measurement, certain measurement errors associated with the system add uncertainty to the measured results. This uncertainty defines how accurately a device under test (DUT) can be measured. This chapter describes how the various network analyzer measurement error sources contribute to uncertainties in the magnitude and phase measurements of both transmission and reflection.
Determining System Measurement Uncertainties Sources of Measurement Errors Sources of Measurement Errors Measurement errors are made up of systematic errors, random errors, and drift errors. Each of these measurement error types is discussed in this section. Sources of Systematic Errors The residual (after measurement calibration) systematic errors result from imperfections in the calibration standards. All measurements are affected by dynamic accuracy.
Determining System Measurement Uncertainties Sources of Measurement Errors Sources of Random Errors The random error sources are noise, connector repeatability and interconnecting cable stability. There are two types of noise in any measurement system: low level noise (noise floor) and high level noise (trace noise). Low level noise is the broadband noise floor of the receiver which can be reduced through averaging or by changing the IF bandwidth.
Determining System Measurement Uncertainties Determining Expected System Performance Determining Expected System Performance Improper connection techniques and contact surfaces can degrade measurement accuracy. Proper connection techniques include using a torque wrench with proper torque limits, ensuring that the connector pin depths meet specifications, ensuring that the center conductor of sliding loads is properly set, and observing proper handling procedures for beadless airlines.
Determining System Measurement Uncertainties Determining Cable Stability Terms (CR1, CR2, CTM1, CTM2, CTP1, CTP2) Determining Cable Stability Terms (CR1, CR2, CTM1, CTM2, CTP1, CTP2) Cable stability is dependent on the cable used and the amount of cable movement between calibration and measurement.
Determining System Measurement Uncertainties Determining Cable Stability Terms (CR1, CR2, CTM1, CTM2, CTP1, CTP2) Figure 10-2 Cable Stability with a Short Connected Figure 10-2 and Figure 10-3 demonstrate the concepts useful in determining cable transmission stability. A short is connected to the free end. The DATA/MEM feature provides an indication of the two-way cable transmission stability.
Determining System Measurement Uncertainties Measurement Uncertainty Equations Measurement Uncertainty Equations Any measurement result is the vector sum of the actual test device response plus all error terms. The precise effect of each error term depends on its magnitude and phase relationship to the actual test device response. When the phase of an error response is not known, phase is assumed to be worst case (–l80° to +180°). Forward Reflection Uncertainty Equation 10-1.
