MODEL 2015-7075 Upconverter
1.0 General
1.1 Equipment Description
The 2015-7075 Upconverter converts 70 ± 18 MHz to 7.0 to 7.5 GHz in 125 kHz steps. Synthesized local
oscillators (LO) provide ±0.01 ppm stability frequency selection. Push button switches select the RF frequency,
gain, and other parameters. Front panel LEDs provide indication of DC power (green), remote operation
(yellow), PLL alarm (red), and TX MUTE (yellow). Variable attenuators for the IF input and RF output provide
a gain range of +10 to +30 dB as adjusted by the front panel pushbutton 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 input and 10MHz reference input and output, and Type N female
for the RF output (other connector configurations available). It is powered by a 100-240 ±10% VAC power
supply; and housed in a 1.75” X 19” X 16” rack mount chassis.

2.4.1 Installing and Operating the 2015-7075 Upconverter
1. Connect a -30 dBm to -10 dBm, 70 MHz signal to IF IN, J4 (Figure 2.2)
2. Connect 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. Make sure the output stays within -20 to 0 dBm with the gain selected
and the input level provided. If the combination of gain and input level settings produce an output
outside of the -20 to 0 dBm range than the spurrious and 1dB compression performance may be
compromised.
7. Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.3).
8. 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 2.4. 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 2.5):
Power Up
Normal Display
Menu 1 Frequency in MHz
Menu 2 Input Level in dBm (-10 to -30)
Menu 3 Gain in dB (+10 to +30 dB)
Menu 4 Mute TX Signal
Menu 5 Set Unit to Remote Operation
Menu 6 Select External 10 MHz Reference
Menu 7 Select RS232, RS422, or RS485 Remote Operation (option Q)
Menu 8 Select RS485 Remote Address for Unit (option Q)
Save Menu When “R” is selected in any of the above menus or when operator reaches the end
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.
2015-7075 Manual_Rev.0 Page 16 02/15/2024

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.

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 changes, the vertical movement will raise or lower the
number in the direction of the arrows.
B. For other functions such as Mute on/off, the vertical switch will alternately turn the
function on or off regardless of the direction operated.
2015-7075 Manual_Rev.0 Page 17 02/15/2024

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 2.5 for
the sequence of menu options. The following display is for changing the upconverter frequency:
F = 7050.000
R
Pressing the Up/Down switch down will toggle the display to:
F = 7150.000
R
By using the horizontal rocker switch the cursor can be moved left or right .
F = 7150.000
R
NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE
MENU AND INDICATE YOU WANT TO SAVE THE CHANGES. THE CARRIER IS MUTED
WHEN FREQUENCY IS CHANGED.
When the display indicates the value desired you can push the Menu/Execute switch to the next item:
INLVL = -10
R
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS? YN
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to the default display:
F = 7250.000 G=+10

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.
To change the 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 2.5 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:
INLVL = -10
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.
Press 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:
G = +10
R
Press the Up/Down switch to change the gain in 1 or 10 dB steps:
G = +15
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 -10 dBm OR HAVE LESS THAN -30 dBm
OUTPUT LEVEL. THE FIRMWARE DOES PREVENT YOU FROM THIS.
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? YN
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to:
F = 7250.000 G=+10
REF=INT
