MODEL 2017-1727-140 Up/Downconverter
1.0 General
1.1 Equipment Description
The 2017-1727-140 L, S-band Up/Downconverter converts 140 ± 20 MHz to 0.95-1.75 GHz GHz (Up) and 2.0-
2.7 to 140 ± 20 MHz (Down) in 1 MHz steps (100 or 125 kHz steps optional). Multi-function switches select
the frequency, gain ( upconverter -10 to +30 dB; downconverter 0 to +50 dB), and other parameters. Front panel
LEDs provide indication of DC power (green), PLL alarm (red), remote operation (yellow), and Upconverter
mute (yellow). Remote operation allows selection of frequency, gain and external 10 MHz reference (option E).
Gain settings appear on the LCD display. Connectors are BNC female for the IF, RF (SMA and N optional) and
optional external reference input and output (option E). A high stability (±0.01 ppm) option (H) 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.

2.0 Installation
2.1 Mechanical
The 2017-1727-140 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 2017-1727-140
can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017-1727-140 is
assembled.

2.4 Installation / Operation
2.4.1 Installing and Operating the 2017-1727-140, 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 in the -40 to -10 dBm range (See Section 2.5 Menu Settings).
6.) Set the gain to get an output level in the -20 to -0 dBm range (See Section 2.5 Menu Settings).
7.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
2.4.2 Installing and Operating the 2017-1727-140, Downconverter Section
1.) Connect a -70 dBm to -20 dBm signal to RF In, J2 (Figure 2.1).
2.) Connect the IF OUT, J1, to the external equipment.
3.) Connect 100- 240 ±10 VAC, 47 - 63 Hz to AC on the back panel.
4.) Set the desired input frequency (See Section 2.5 Menu Settings).
5.) Set the gain to get an output level in the -30 to -10 dBm range (See Section 2.5 Menu Settings)
6.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
7.) AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot in
the drawer below the AC input as shown in Figure 2.3. There is a spare fuse in the near slot. If a fuse
continues to open, the power supply is most likely defective.

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 2.4):
Power Up
Normal Display
Menu 1 Up Frequency in MHz
Menu 2 Up Input Lvl (Set from -40 to -10)
Menu 3 Up Gain (+30 to -10)
Menu 4 Down Frequency in MHz
Menu 5 Down Gain (set +50 to 0 for -20 to -10 dBm out range)
Menu 6 Up Mute
Menu 7 Set Unit to Remote Operation
Menu 8 Set Downconverter Spectrum Sense
Menu 9 Select External 10 MHz Ref (option -E)
Menu 10 Set RS-485 mode (option -Q)
Menu 11 Set RS-485 address (option -Q)
Menu 12 View PCB Temperature (option -T)
Save Menu At the end or when “R” is selected from any of the above menus
Alarm indications appear on the LEDs (see figure 2.2).
All program changes must start with the operation of the Menu/Execute switch and must also end with the
operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed,
none of the changes will take effect. If programming is initiated and no operator action takes place for
approximately 12 seconds (before the final press of the Menu/Execute switch) the display will revert to its
previous status and you will need to start over.
2017-1727-140 Manual, Rev. 0 Page 12 02/14/18

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 and gain of the up and downconverter is shown.
U F=1725 G=+10.0
D F=2675 G=+25.0
The unit is now operational and ready for any changes the operator may desire.
2.5.3 Control Switches
1. Menu/Execute - Any change to the programming of the unit must be initiated
by pressing the Menu/Execute switch and completed by pressing the Menu/Execute switch.
2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves
the cursor left or right.
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.
2017-1727-140 Manual, Rev. 0 Page 13 02/14/18

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 2.4 for
the sequence of menu options). The following display is for changing the upconverter frequency:
UP F = 1725.000 R
Pressing the Up/Down switch down will toggle the display to:
UP F = 1725.000 R
By using the horizontal rocker switch the cursor can be moved left or right.
UP F = 1725.000 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 = -20R
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 Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to the :
U F=1725 G=+10.0
D F=2675 G=+25.0
Figure 2.4 shows all the menu items and how to make changes.
2017-1727-140 Manual, Rev. 0 Page 14 02/14/18

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.
2.5.5.1 Upconverter Gain
To set the upconverter 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 upconverter input level. This is an important setting to
optimize spurious and should be made as accurately as possible:
UP INLVL = -20R
Pressing the Up/Down switch to change the level in 1 dB steps and then push the Menu/Execute switch
to get to the Gain setting:
UP G = +10.0 R
By using the horizontal rocker switch the cursor can be moved left or right .
Pressing the Up/Down switch down will toggle the display digit selected until you have the desired gain.
NOTE: THE GAIN WILL BE CHANGED AS YOU ADJUST THE NUMBERS. HOWEVER, THE
VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE SETTINGS
WINDOW. DO NOT SET A GAIN THAT WOULD EXCEED A 0 dBm OUTPUT LEVEL.
When the display indicates the value desired you can push the Menu/Execute switch to the next item
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS? Y N
