STARLINE 11
The RF cable should be approximately eight inches long and have red boots on the connector
signifying the return path.
8
If necessary, connect the appropriate return RF cables from the SG4-RF modules to each 2X
redundant return board.
9
Ensure that the PIC cable is properly connected to the lid and power distribution board in
the housing base.
10
Route and connect the fiber service cable.
11
Apply power to the node. Allow five to ten seconds for the system self-diagnosis to complete.
12
Verify that the green LED (
ENABLE
), located on the top panel of each SG4-DRT-2X is
illuminated to confirm enable status.
11
Measure the RF power at each channels test point on the top of each SG4-DRT-2X.
The test point is a
−
20 dB test point located after the JXP pad location and indicates the
level into the SG4-DRT-2X.
12
Place the proper JXP pad into each SG4-DRT-2X pad facility to achieve the nominal total
power level at the test point of
−
5 dBmV.
13
Review return path system levels.
The SG4-DRT-2X is configured to drive the laser to the recommended level (
+
15 dBmV)
when the total combined power at the housing ports connected to the 2X redundant return
board is approximately
+
28 dBmV.
14
Measure the optical power level at the dc test point using a multimeter. The scaled voltage
at this test point is 0.5V/mW.
