MODEL 2017-95 Up/Downconverter 1.0 General 1.1 Equipment Description The 2017-95 L-band Up/Downconverter converts 70 MHz to 250-950 MHz (Up) and 250-950 MHz to 70 MHz (Down) in 1 MHz steps with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-function push button switches select the RF frequency, gain, and other parameters.

1.4 Environmental Use Information A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions located in the user manual furnished by the manufacturer of your equipment rack. B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution. C.
2.0 Installation 2.1 Mechanical The 2017-95 consists of one RF/Controller PCB housed in a 1 RU (1.75 inch high) by 16 inch deep chassis. A switching, ± 12, +5, +24 VDC power supply provides power for the assemblies. The 2017-95 can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017-95 is assembled. POWER SUPPLY Figure 2.
2.2 Rear Panel Input/Output Signals and Control - Figure 2.1 shows the input and output connectors on the rear panel. AC1 - POWER IN AC input for switching power supply. 100-240 ±10% VAC, 47-60 Hz. F1 - LNB FUSE (option -L) 0.5A, Fast Blo, 1/4” Fuse; installing fuse places +24 VDC, 0.4 Amps, max on the RF IN (J2 center pin). J2 - RF IN 250-950 MHz input, -70 to -20 dBm, see Table 2.2. AC J1 - IF OUT 70 MHz output, -20 to 0 dBm, see Table 2.2. J10 - MONITOR AND CONTROL DB9 female connector. see Table 2.
2.3 Front Panel Controls and Indicators - The following are the front panel controls and indicators. DS3 - DOWN ALARM LED Red LED indicates Downconverter alarm. LCD DISPLAY Display shows Up and Downconverter frequency in MHz and Gain in dB DS1 - REMOTE LED Yellow LED indicates remote operation.

2.4 Installation / Operation 2.4.1 Installing and Operating the 2017-95, 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.) Set the gain to get an output level in the -10 to +30 dBm range (See Section 2.5 Menu Settings). 7.

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 = 475 G=+10.0 D F = 625 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 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.
