Forward Path RF Verification
1 Install the RF module into the test GS7000 Node housing.
2 Verify the location of any AC Power shunts prior to applying AC Power.
2 Verify the location of any AC Power shunts prior to applying AC Power.
Note that AC Power must be connected to port with a shunt installed and the AC
Power will be also present at all other ports with shunts installed.
Energize the unit only after verifying the AC shunt configurations.

Energize the unit only after verifying the AC shunt configurations.
3 Attach a network analyzer or stealth meter to output port of the RF Amp
module (or to Forward Test Point location).
4 Note that the amplifier gain will be approximately 42dB (or 22 dB if measuring
at test point location) in this configuration and analyzer port power setting will
need to be set appropriately to prevent overdriving the unit or the analyzer.
