Operational Monitoring
When the amplifier is in normal operation, the console will output the forward and reflected power ratio
for every transmission in the following format:
fwd/rev ratio, 1815.7
fwd/rev ratio, 1210.0
fwd/rev ratio, 930.3
fwd/rev ratio, 1632.6
fwd/rev ratio, 490.5
fwd/rev ratio, 577.0
fwd/rev ratio, 708.2
The ratio number will change based upon hardware conditions, environmental conditions and overall power
output, but the ratio number is not directly related to a percentage or power value. It is best used as a long term
indicator of the heath of the transmission system. As the number approaches 0 (lower ration numbers) the higher
the reflected power is detected. There is a software command (reflect
–
see below for full details) that will set a
minimum acceptable ratio before the stops amplifying the RF energy for self-preservation.
