MODEL 3116-7786-2150 Downconverter
1.0 General
1.1 Equipment Description -The 3116-7786-2150 Downconverter converts 7.75 - 8.65 GHz (Fc = 7.9 - 8.5
GHz) to 2150 ± 150 MHz (non-inverted) in 1 MHz steps (100 kHz, 125 kHz steps optional) with a 5.75 - 6.35
GHz local oscillator. The gain is +35 dB maximum with a 30 dB adjustment in 0.5 ±0.5 dB steps. Front panel
LEDs provide indication of Remote operation, PLL Alarm and DC Power. Frequency and
internal/external/Auto reference mode selection are controlled by front panel switches or remote selection (via
RS-232C/485, standard; Ethernet Optional) and are viewable on the LCD Display. Connectors are Type N
female for the RF and BNC female for the L-Band and external reference input and reference output. In AUTO,
the 10 MHz reference stays in external if the external level is +3 dBm, ±3 dB. The 3116 is powered by a 100-
240 ± 10% VAC power supply, and housed in a 1 3/4” X 19” X 14” rack mount chassis.

2.4 Installation / Operation
2.4.1 Installing and Operating the 3116-7786-2150 Downconverter
1.) Connect a -55 dBm to -35 dBm signal to RF INPUT, J101 (Figure 2.1).
2.) Connect the L-BAND OUTPUT, J1, to the external equipment.
3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC connector on the back panel.
4.) Set the gain (+35 dB maximum with a 30 dB adjustment in 0.5 ±0.5 dB steps.)
Make sure the output stays within -20 to 0 dBm with the gain
selected and the input level provided. (See Section 2.5 Menu Settings).
5.) Be sure the green DC Power is on and the red Alarm is off (Figure 2.2).
6.) 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):

Menu 4 Set Reference Mode
Menu 5 Set Reference Offset
Menu 6 Set Remote
Menu 7 Set Remote Interface
Menu 8 Set RS-485 Address
Save Menu When “R” is selected from any above menu or at 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 30 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.
3116-7786-2150 Manual, Rev. 0 Page 12 11/24/20

2.5.2. Power On Settings
NOTE: THE LAST OPERATING PARAMETERS OF A UNIT ARE 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 Model and Software version will be displayed.

3. The present frequency and gain of the upconverter is shown.
FC = 8200.000
G = +10 REF AUTO - I
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
display cursor left or right.
3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions:
a. During gain changes, the vertical movement will raise or lower the number
in the direction of the arrows.
b. For other functions such Remote on/off, the vertical switch will alternately turn the function
on or off regardless of the direction operated.

External Mode: The unit uses a 10 MHz Reference that is connected to the External Reference Input, J2.
REF = EXT appears on the front panel display. The External 10 MHz Reference level
must be +3dBm, ±3dB. If the External 10 MHz signal does not meet the unit’s
specified parameters then the unit will not function properly. The External Reference
is present on the Reference Output connector, J8.
Auto Mode: The unit defaults to the External 10 MHz Reference as long as the level meets the +3dBm,
±3dB specification. REF = AUTO - E appears on the front panel display where the -E
indicates that the unit is using the External 10 MHz Reference. The External Reference is
present on the Reference Output connector, J8.
If the external 10 MHz Reference signal level is less than -1dBm, the unit switches to
Internal 10 MHz Reference. REF = AUTO -I appears on the front panel display
where -I indicates that the unit is using the Internal 10 MHz Reference. The Internal
10 MHz Reference is present on the reference output connector, J8.

3.0 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.Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Additional space between units
may be required.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used, when addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or
EGRESS emission problems.
