TM 11-5895-846-14
C-2.
Overall Receiver Gain.
NOTE
The overall receiver gain is calibrated
using signal sources within the
terminal in conjunction with precision
attenuator and a low level SHF hard
is obtained from the SHF local
synthesizer in the upconverter
drawer.
The output level of this
signal is between the limits of + 6 and
+ 12 dBm and is passed through the
SHF hard limiter and attenuator to
provide a -52 dBm signal at the 20 dB
coupler on the AME subassembly,
which gives a nominal 72 dBm signal
at the LNA input.
