MODEL 3117-3338#-720 Up/Downconverter
1.0 General
1.1 Equipment Description
The 3117-3338#-720 Up/Downconverter converts 0.72 to 3.3 and 3.8 to 0.72 GHz (±0.3 GHz) with non-inverting spectrums. Front
panel LEDs provide indication of Remote, DC Power, upconverter mute, and PLL Alarm. The maximum gain is +20 dB for the
upconverter and +20 dB for the downconverter (adjustable in 0.5 ± 0.5 dB steps). Gain and internal/external/Auto reference frequency
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 DOWN IN and RF UP OUT and BNC female for the RF UP IN, RF
DOWN OUT 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 3117 is powered by a 100-240 ± 10% VAC power supply, and in a 1 3/4” X 19” X 14” rack mount chassis.

2.4 Installation / Operation
2.4.1 Installing and Operating the 3117-3338#-720, Upconverter Section
1.) Connect a -40 dBm to -20 dBm signal to RF 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 gain (See Section 2.5 Menu Settings).
5.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
2.4.2 Installing and Operating the 3117-3338#-720, Downconverter Section
1.) Connect a -40 dBm to -20 dBm signal to RF In, J2 (Figure 2.1).
2.) Connect the RF OUT, J1, to the external equipment.
3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC on the back panel.
4.) Set the gain to get the desired output level.
5.) Be sure DS6 (green, DC Power) is on and DS3 (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.
3117-3338#-720 Manual, Rev. 0 Page 12 03/23/2022

2.4.3 External 10 MHz Reference Operation
Internal Reference Mode
When the internal reference mode is selected, the unit's internal 10 MHz reference will become the ‘primary’
source and the unit’s synthesizers will lock to this internal 10 MHz reference. The unit will ignore any external
10 MHz signal present on the external reference input (J3). The unit will also buffer the internal 10 MHz signal
and provide it on the Reference Out connector (J18) at +3 dBm, +/- 3 dB.
External Reference Mode
When the external reference mode is selected, the external 10 MHz reference (received on J3) will become the
‘primary’ source and the unit’s synthesizers will lock to this external 10 MHz reference. The unit must have a
10 MHz signal connected to the external reference input (J3) on the rear panel. The external 10 MHz signal
must be +3 dBm, +/- 3 dB. The unit will also buffer the external 10 MHz signal and provide it on the Reference
Out connector (J18) at +3 dBm, +/- 3 dB.
Auto Reference Mode
When the auto reference mode is selected the unit will detect and select the external 10 MHz signal if it is
present and at least +3 dBm. If the external 10 MHz signal falls below 1 dBm (+/- 1 dB) the unit will
automatically switch to the internal 10 MHz reference. The reference out connector (J18) provides a buffered
rendition of the selected 10 MHz signal at +3 dBm, +/- 3 dB.

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 2.2):
Power Up

Menu 1 Up Gain (0 to 20.0)
Menu 2 Down Gain (0 to 20.0)
Menu 3 Up Mute
Menu 4 Reference Mode
Menu 5 Remote
Menu 6 Interface
Menu 7 RS485 Address (0 to 31)
Menu 8 Reset Ethernet Settings
Save Menu When go to 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.

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 (Maximum Recommended Ambient Temperature).
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 unit
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
