MODEL 2017-03 Up/Downconverter
1.0 General
1.1 Equipment Description
The 2017-03 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. Synthesized local oscillators
(LO) provide frequency selection. Multi-function push button switches select the RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL alarm for up and downconverters
(red), remote operation (yellow), and Upconverter mute (yellow). Gain can be manually controlled over a -10 to
+30 dB range for the Upconverter and over a 0 to +50 dB range for the Downconverter as adjusted by the front panel multi-function push-button switches. Remote operation allows selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD display. Connectors are BNC female for IF and the optional external reference input and output, and Type F female for RF. LNB or SSPB +24 VDC and 10
MHz reference can be inserted on the RF lines as added options. A high stability (±0.01ppm) option is also available. It is powered by a 100-240 ± 10% VAC power supply and housed in a 1.75” X 19” X 16” 1RU chassis.

3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions: a. During frequency , gain, input level changes, the vertical movement will raise or lower the number in the direction of the arrows.
b. For other functions such Mute on/off, the vertical switch will alternately turn the function on or off regardless of the direction operated.
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.
2017-03 Manual, Rev. N Page 16 03/22/18
To change the FREQUENCY:
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 Upconverter frequency:
UP F = 1350 R
Pressing the Up/Down switch down will toggle the display to:
UP F = 1450 R
By using the horizontal rocker switch the cursor can be moved left or right.
UP F = 1450 R
NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE
MENU AND INDICATE YOU WANT TO SAVE THE CHANGES.
When the display indicates the value desired you can push the Menu/Execute switch to the next item:
UP INLVL = -20 R
NOTE: CHANGES TAKE PLACE ON LEVEL AND GAIN IMMEDIATELY BUT DO NOT GET
SAVED UNTIL YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE
CHANGES.
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS?
Y N
Selecting Y will save the new settings. Selecting N will revert to the previous settings.
Pushing the Menu/Execute switch then takes you to the :
U F=1450 G=+10.0
D F=1250 G=+20.0
Figure 2.4 shows all the menu items and how to make changes.
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
