RF Levels Screen
This screen allows the user to change settings to the RF levels, including the Forward RF level
and the reflected (VSWR) trip point. From this screen, the user can also toggle between AGC
and Manual mode. The RF Levels Screen is displayed below:
To adjust Forward RF Level:
Press the up or down arrows until the desired Forward RF level is reached. If the adjusted level
exceeds 110%, the protection will kick in and the system will fold back the RF power to a safe
level. There may be a residual amount of Forward power even at 0% setting, but it should be
insignificant.
To toggle between Manual and AGC Mode:
Simply press the CHANGE TO MANUAL or CHANGE TO AGC button in the Adjust Levels half
of the screen. If a fault occurs while in AGC mode, the system will default back to Manual mode
and protective action will be taken.
NOTE: Pressing the up and down arrows for Forward RF level change while in AGC will
change the power. The same holds true for Ethernet, SNMP, or Remote Port control The AGC
is designed to hold the RF power level steady when the system is unmanned for external events
like temperature, slight changes to the input level, and long term component fatigue.
To change the VSWR Shutdown Trip Point:
Use the up and down arrows to set the VSWR shutdown trip point to between 1.1:1 and 1.8:1. If
a measured VSWR is found above the set trip point, but below 1.8:1, then the system will fold
back the forward power to a safe level. If the measured VSWR exceeds 1.8:1, then the carrier
will be initially turned right off.
