STEPS ACTION MISCELLANEOUS
8.
Record the new 20dB quiet value of AC
Level on worksheet together with its
associated RF input level
10
.
9.
Replace the 50-Ohm Terminator with the
main receive antenna feed. The indicated
value of AC Level will increase.
10.
Increase the RF input Amplitude to recover
the reading recorded on the worksheet.
11.
Calculate the difference between readings
obtained with Antenna versus the 50-ohm
Terminator to obtain the 20dB de-sense
value. Record this on the worksheet and
record the results on the datasheet.
12. Repeat for all other channels.
If the Site Noise on all RX Channels
exceeds 5 dB or if a single channel
exceeds 5 dB contact M/A-COM
Engineering.
