More Information
(not currently in use)
(not currently in use)
(not currently in use)
The maximum input power at the T/R
port has been exceeded. Accurate
measurements cannot be made, please
reduce the input level
Reverse power detected at the Gen
output port. Please remove the reverse
power.
Full Bypass Enable is selected, which
means that when the Low Noise Path
switches in (when Start Freq >3.6 GHz
and the Preamp is either not licensed,
set to Low Band or Off) and Attenuation
is set to 0 dB, there will be a direct AC
connection between the input and the
first converter, which puts the first
converter at high risk to be damaged
by high AC power. Keep the power at
the input below +20 dBm.
User is cautioned that in this mode,
high power at the T/R input can cause
damage to the input circuitry
