MODEL 2015-123 Upconverter
1.0 General
1.1 Equipment Description
The 2015-123 Upconverter converts 70 ± 18 MHz to 2025 to 2300 MHz in 1kHz, 10kHz, or 125kHz steps (user
selectable) with low group delay and flat frequency response. Synthesized local oscillators (LO) provide very
low phase noise and ±0.01 ppm stability 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 (red), remote operation (yellow) or the TX carrier is muted (yellow). Variable attenuators for the IF input
and output provide a gain range of -10 to +30 dB 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 Input, RF outputs and the 10MHz
external reference input and 10MHz reference output. The 10MHz reference signal (internal or external) can be
sent to the 10MHz reference output connector and/or to the RF OUT connectors. The RF signal can be
switched between two RF outputs (A and B) via an integrated, remotely controlled RF switch.. The unit is
powered by a100-240 ±10% VAC power supply, and is housed in a 1.75” X 19” X 16” rack mount chassis.

2.4 Installation / Operation
2.4.1 Installing and Operating the 2015-123 Upconverter
1.) Connect a -10 dBm to -40 dBm, 70MHz signal to IF IN, J4 (Figure 2.2)
2.) Connect the RF OUT A, J101, and RF OUT B, J102, to the external equipment.
3.) Connect 90- 260 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. The firmware will prevent setting gain and input level outside this
range. (See Section 2.5 Menu Settings).
7.) Select the RF Output (A or B) (See Section 2.5 Menu Settings).
8.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.3).
9.) 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.

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.
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, gain, and selected RF output of the upconverter is shown.
F = 2050.000
G = +00.0 RF = A
The unit is now operational and ready for any changes the operator may desire.
2015-123 Manual, Rev.A Page 11 11/12/09

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 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.
To change the FREQUENCY:
1.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 = 2050.000
R
Pressing the Up/Down switch down will toggle the display to:
F = 2150.000
R
By using the horizontal rocker switch the cursor can be moved left or right .
F = 2150.000
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:
UP INLVL = -20
R
2015-123 Manual, Rev.A Page 12 11/12/09

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 = 2150.000
G = +00.0 RF = A
Figure 2.5 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
“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:
1.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:
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.
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 = +00.0
R
Press the Up/Down switch to change the gain in 0.1, 1 or 10 dB steps:
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.
2015-123 Manual, Rev.A Page 13 11/12/09

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 0 dBm OR HAVE LESS THAN -20 dBm
OUTPUT LEVEL. THE FIRMWARE PREVENTS 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 = 2150.000
G = +10.0 RF = A
Figure 2.5 gives the menu items and how to make changes
2.5.5 Alarm Indications
An alarm condition for will occur if the local oscillator phase lock loop (PLL) comes out of lock. The Mute
LED will light if you select to mute the Tx Signal and the Remote LED will light when you select the Remote
mode.
