MODEL 2017-03A Up/Downconverter 1.0 General 1.1 Equipment Description The 2017-03A L-band Up/Downconverter converts 70 MHz to 950-1525 MHz (Up) and 950-1525 MHz to 70 MHz (Down) in 1 MHz steps with low group delay and flat frequency response. The 2017-03A has lower RF level out of the upconverter and higher RF level into the downconverter than the 2017-03 and is typically used to interface an L-band modem to a 70 MHz IF upconverter and downconverter.

1.4 Environmental Use Information A. Elevated operating ambient temperature - if installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack may be greater than room ambient temperature. Therefore, consideration should be given to Tmra. B. Reduced air flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Additional space between unit may be required. C.
2.0 Installation 2.1 Mechanical - The 2017-03A consists of one RF/Controller PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis. A switching, ± 12, +5, +24 VDC power supply provides power for the assemblies. The 201703A can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017-03A is assembled. POWER SUPPLY Figure 2.0 2017-03A Manual, Rev.
2.2 Rear Panel Input/Output Signals and Control - Figure 2.2 shows the input and output connectors on the rear panel. AC1 - POWER IN AC input for switching power supply. 100-240 ± 10% VAC, 47-63 Hz. J2 - RF IN 950-1525 MHz input, -60 to -10 dBm, see Table 2.2.

2.4 Installation / Operation 2.4.1 Installing and Operating the 2017-03A, Upconverter Section 1.) Connect a -40 dBm to -10 dBm signal to IF In, J4 (Figure 2.1). 2.) Connect the RF OUT, J5, to the external equipment. 3.) Connect 100 - 240 (±10% VAC), 47 - 63 Hz to AC 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.) (option V) To power the SSPB (+24 VDC, 2.5 amps max.) from the 2017-03A install a 2.

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. REV1.00 3. The present frequency and gain of the up and downconverter is shown. U F=1350 G=+00.0 D F=1250 G=+20.
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: Operate the Menu/Execute switch until you get to the menu item you want to change (see Figure 2.
2.5.5 Gain/Level 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.
2.5.5.2 Downconverter Gain To set the downconverter gain, first push the Menu/Execute switch to get to the gain setting: Operate the Menu/Execute switch until you get to the menu item you want to change see Figure 2.4 for the sequence of menu options. The following display is for changing the downconverter gain. This is an important setting to optimize spurious and should be made as accurately as possible to provide an output in the -10 to 0 dBm level range: DN G = +30.
