MODEL 2015-24 Upconverter 1.0 General 1.1 Equipment Description The 2015-24 L-band Upconverter converts 140 ± 36 MHz to 950 to 2150 MHz in 1kHz, 10kHz, 100kHz, or 125kHz steps (user selectable) with low group delay and flat frequency response. Synthesized local oscillators (LO) provide very low phase noise and ±0.01 ppm stability frequency selection. Multifunction push button switches select the RF frequency, gain, and other parameters.

B) Status Requests Table 1.2 lists the status requests for the 2015-24 and briefly describes them. * PLEASE NOTE: The two character {aa}(00-31) prefix, in the table below, should be used ONLY when RS-485, (OPTION-Q), is selected. TABLE 1.
C) Commands Table 1.3 lists the commands for the 2015-24 and briefly describes them. After a command is sent the 2015-24 sends a return “>” indicating the command has been received and executed. General Command Format - The general command format is {aaCND...
2.0 Installation 2.1 Mechanical The 2015-24 consists of one RF/Controller PCB which is housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis. A switching, ± 12, +24, +5 VDC power supply provides power for the assembly. The 2015-24 can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2015-24 is assembled. POWER SUPPLY FIGURE 2.1 2015-24 Mechanical Assembly 2015-24 Manual_Rev.
2.2 Rear Panel Input / Output Signals Figure 2.2 shows the input and output connectors on the rear panel. J10 - MONITOR AND CONTROL DB9 female connector. see Table 2.1. J3 - 10 MHz EXT REF INPUT (Option -E) 10 MHz external reference input, +3 ± 3 dBm, 50Ω/75Ω, BNC female connector. F2 - SSPB FUSE (option -V) 2.5A, Fast Blo, 1/4” Fuse; installing fuse places +24 VDC, 2.5 amp, max on the RF OUT (J5 center pin).
2.3 Front Panel Controls and Indicators Figure 2.3 shows the front panel controls and indicators. IF MONITOR IF, 50Ω BNC Monitor Port IF MONITOR LCD DISPLAY Display shows frequency in MHz and Gain in dB RF MONITOR RF, 50Ω SMA Monitor Port S1 - MENU/EXECUTE BUTTON Press this to get into Program mode and to execute any changes. RF MONITOR F=1450.000 G=+10.
2.4 Installation / Operation 2.4.1 Installing and Operating the 2015-24 Upconverter 1. Connect a -40 dBm to -10 dBm, 140 MHz signal to IF IN, J4 (Figure 2.2) 2. Connect the RF OUT, J5, to the external equipment. 3. Connect 100-240 ±10% VAC, 47 - 63 Hz to AC input on the back panel. 4. Set the desired output frequency (See Section 2.5 Menu Settings). 5. Set the input level (See Section 2.5 Menu Settings). 6. Set the gain for -10 to +30 dB.
2.5 Menu Settings 2.5.1 Functions - This section describes operation of the front panel controls. There are three operator switches, the LCD display and alarm indicator LEDs. All functions for the equipment are controlled by these components. The functions are (see Figure 2.
2.5.2. Power On Settings NOTE: The last status of a unit is retained even when power is removed. When power is restored, the unit will return to it's previous settings. When power is first applied, the LCD display goes through three steps. 1.The LCD goes black to show all segments are functioning. 2.The software version will be displayed. REV 1.00 3.The present frequency, gain, and selected RF output of the upconverter is shown. F = 1450.000 G = +10.
2.5.4 Frequency Changes At any time during the modification process, if you have made a mistake and do not wish to save the changes you have made, do not press the Menu/Execute switch; simply do nothing for approximately 12 seconds, and the system will return to the normal operating mode or scroll to “R” and push the menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window. To change the FREQUENCY: 1.Operate the Menu/Execute switch until you get to the menu item you want to change see Figure 2.
2.5.5 Gain Changes When you get to this menu note that the gain changes will be made as you make them but if you do not wish to save the changes you have made, scroll to “R” and push the menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for approximately 12 seconds, and the system will return to the normal operating mode.
2.5.5 Alarm Indications An alarm condition for will occur if the local oscillator phase lock loop (PLL) comes out of lock. The Mute LED will light if you select to mute the Tx Signal and the Remote LED will light when you select the Remote mode.
