RECEIVE FIELD ALIGNMENT (AS-3199)
For field alignment of the receive, the following test
equipment and cables are required:
Hard Limiter, SM-A-934943
is obtained from the SHF local
Cable Assembly, SM-C-935488-1
6 dB Attenuator, SM-A-937237-3

in
the
14 dB Attenuator, SM-A-937237-1
upconverter drawer. The output level
Power Meter, HP-436A with HP-8484A Head and
of signal is between the limits of +6
HP-8481A Head
and +12 dBm. The signal is passed
through the SHF hard limiter and
C-1.
Low Noise Gain/Slope Adjustment

The low noise gain/slope is adjusted
using signal sources within the
electronic subassembly and at the
terminal in conjunction with precision
LNA input.
