7 Ensure that the PIC cable is properly connected to the lid and power distribution board in
the housing base.
8 Route and connect the fiber service cable.
9 Apply power to the node. Allow five to ten seconds for the system self-diagnosis to complete.
10 Verify that the green LED ( ENABLE ), located on the top panel of the SG4-DRT-2X is
illuminated to confirm enable status.
11 Measure the RF power at each channels’ test point on the top of the SG4-DRT-2X.
The test point is a
−20 dB test point located after the JXP pad location and indicates the
level into the transmitter.
12 Place the proper JXP pad into each channels’ 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 split 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.
