Press (ESC) to cancel the reference value input, and the multimeter will return back to the submenu level without changing the reference value. 5. Press NOTE: → key to exit the menu and return to the dB math operation. The reference impedance and input impedance mentioned in this chapter are completely different.
Measurement Options Chapter 4 Measurement Options This chapter is outlined as follows: 4.1 Measurement configuration 4.2 Trigger Operations 4.3 Buffer Operations 4.4 Limit Operations 4.5 System Operations 4.1 4.1.1 Measurement configuration Range You can let the multimeter automatically select the range using auto ranging or you can select a fixed range using manual ranging. Auto ranging is convenient because the multimeter automatically selects the appropriate range for each measurement.
Measurement Options 4.1.2 Filter FILTER lets you set the filter response to stabilize noisy measurements. The multimeter uses a digital filter. The displayed, stored and transmitted readings are simply an average of a number of reading conversions (from 1 to 100). Perform the following steps to select a filter: 1. Press → to enter the menu on the menu level, “A: MEAS MENU” will be displayed. 2. Press to move down to the submenu level within the MEAS MENU, “1: CONTINUITY” will be displayed. 3.
Measurement Options the oldest conversion is discarded, and the stack is re-averaged, yielding a new reading. See Figure 4-1 below. B. Repeat Average (REPEAT) For the repeating average filter, the stack is filled and the conversions are averaged to yield a reading. The stack is then cleared and the process starts over as shown in Figure 4-1.
Measurement Options displayed offset becomes the reference value. Subtracting the offset from the actual input, the display will be as follows: Displayed reading = Actual Input – Reference Selecting a range that cannot accommodate the relative value does not cause an overflow condition, but it also does not increase the maximum allowable input for that range. For example: on the 1.2 V range, the meter still overflows for a 1.4 V input.
Measurement Options 4.2 Trigger Operations The multimeter’s triggering system allows you to generate triggers either manually, automatically, or externally for taking multiple readings per trigger. The following discusses front panel triggering, programmable trigger delay, and the reading hold feature. 4.2.1 Trigger Model The flowchart below (Figure 4-2) summarizes the triggering process of the instrument.
Measurement Options 1. A bus trigger (*TRG) command is received via remote control. 2. The front panel key is pressed (The meter must be in local mode first). Trigger Source The trigger source can be set from the front panel trigger menu. Users can select either IMM, MAN, BUS, or EXT. Description of each are as follows: IMM: Immediate. Event detection happens immediately and will continue making measurement continuously. MAN: Manual. Even detection happens when the front panel key is pressed.

Measurement Options 4.2.2 EXT Trig & VM Comp The rear panel of the instrument has two BNC terminals: Ext Trig and VM Comp. This section describes the functionality of these two terminals. Ext Trig This is the external trigger input terminal. When trigger mode is set to EXT, this terminal can be used as the source for triggering a measurement. Input a negative pulse into this terminal to trigger the instrument. The pulse width must be greater than 1 μs. An example is illustrated in Figure 4-3 below.
Measurement Options saved through a power cycle. Note: Readings will not include the function (i.e. VDC, VAC, Frequency, etc.) or the unit of measurement (i.e. V, A, Hz, Ω, etc.) selected prior to storing into the buffer. 4.3.1 Store Reading Select a measurement function and any math operations first, then connect the test leads to the signal under test. Setup the reading speed (FAST, MED, SLOW), then use the following procedure to store readings: 1. 2. 3. 4. 5.
Measurement Options Warning: Readings inside the buffer are volatile. Therefore do not power off the instrument or data will be lost. Additionally, each time the store reading function is enabled and initialized, previously stored data in the buffer will be overwritten. 4.3.2 Recall Readings Use the following steps to recall the stored readings and their statistical information (minimum, maximum, average, and standard deviation): 1. 2. 3. 4. 5. 6.
Measurement Options 4.3.3 Buffer Statistics In addition to measured readings that can be stored into the internal buffer, four other statistical information of the stored readings are also kept inside the buffer. They are: MAX, MIN, AVG, STD. MAX and MIN The MAX and MIN refer to the maximum and minimum value of the readings stored in the buffer respectively. For example, suppose the buffer contains the following five readings: 1.234, 2.345, 3.456, 4.567, 5.678. MAX = 5.678 MIN = 1.
Measurement Options A 0.6kΩ reading becomes 600Ω (HI). When the reading is within the configured limit range specified by low and high limits, “IN” will be shown after measured display. If it is higher than the limit range, “HI” will be shown after the measured display. Similarly, if it is lower than the limit range, “LO” will be shown.

SCPI Command Reference Chapter 6 SCPI Command Reference This chapter is outlined as follows: 6.1 Command Structure 6.2 Command Syntax 6.3 Command Reference 6.1 Command Structure The remote commands are divided into two types: Common commands and SCPI commands. The common commands are defined in IEEE std. 488.2-1987, and these commands are common for all devices. Not all commands are supported by the 5492B, and some commands are not supported by the GPIB interface for the 5492BGPIB.
SCPI Command Reference 6.2 6.2.1 Command Syntax Commands and command parameters Common commands and SCPI commands may or may not use a parameter. The following are some examples: *RST No parameter used :FORMat Parameter required :IMMediate No parameter used For commands that use a parameter, include a space in between the command and the parameter. Brackets [ ]: Some command words are enclosed in brackets.
SCPI Command Reference = MOVing REPeat :RESistance:AVERage:TCONtrol MOVing Numeric Representation format: This parameter is a number that can be expressed as an integer (e.g., 6), a real number (e.g., 25.3) or an exponent (e.g., 5.6E2). Example: :MMFactor 5 Numeric value: A numeric value parameter can consist of a NRf number or one of the following name parameters: DEFault, MINimum, MAXimum. When DEFault parameter is used, the instrument is programmed to the *RST default value.
SCPI Command Reference 6.2.3 Basic Rules of Command Structure Commands are not case sensitive. For example: FUNC:VOLT:DC = func:volt:dc = Func:Volt:Dc Spaces (︺ is used to indicate a space) must not be placed before and/or after the colon (:). For example: (wrong) FUNC︺:︺VOLT:DC (right) FUNC:VOLT:DC The command can be completely spelled out or in abbreviated type. (In the following description, short form will be printed in upper case.
SCPI Command Reference When the path pointer detects a colon (:) after a semicolon (;), it resets back to the root level. The path pointer can only move down. It cannot be moved up a level. Executing a command at a higher level requires that you start over at the root command. 6.3 Command Reference The following are the subsystem commands: DISPlay CALCulate SENSe SYStem UNIT TRIGger The supported common commands are: 6.3.
