2.3 Input / Output Signals
Figure 2.3 shows the input and output signals to the 2009-2425-1750.
J1 - RF IN
The 2..40 to 2..50 GHz input .
This must be a “clean” input with no
image or other frequency present.
The max input level is -20 dBm.
This is a 50
Ω
, Type N, female
connector.
J3 - DC POWER
The +15 VDC unregulated DC voltage from
the wall power supply. -P models ONLY.
J2 - IF OUT
The 1700 -1800 to 1450
MHz output at -10 dBm
max level with -20 dBm in.
This is a 75
Ω
, Type F,
female connector. May
also c15 to +18
GND +15

2.4 Accessing the PC Card
There are NO USER JUMPERS or other on-card controls. ALTHOUGH IT IS NOT RECOMMENDED AND
MAY VOID THE WARRANTY the following shows how to remove the printed circuit board (PCB) from the
extrusion:
1. Always remove power when installing or removing the PCB from the extrusion
2. Remove four (4) rear panel screws (see Figure 2.1).
3. Gently pull the rear panel and PCB assembly completely out of the extrusion.
4. To install the PCB, gently push the rear panel and PCB assembly completely into the extrusion
(make sure the shield goes in the lower channel and the PCB in the next channel above that) and that
the front panel indicators line up with the front panel holes.
5. Install four (4) rear panel screws.
2.5 Installation / Operation
2.5.1 Installing and Operating the 2009-2425-1750:
1. For -P4 models, connect one end of the Wall Power Supply to the 2009-2425-1750 DC
Power In, J3, and the other end to 115 VAC, 60 Hz (Figure 2.3).
2. Connect a -20 dBm, maximum, signal to RF IN, J1 (Figure 2.3).
3. Connect the IF OUT, J2, to the receiver under test (For models powered from the LNB be sure that
the LNB voltage is +15 to +18 VDC, 250 ma) (Figure 2.3).
4. Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
