5-5.1.4 Spurious Test
8. With the power amplifier set at 180 watts power output, use the spectrum analyzer and check
the frequency band from 869 MHz to 894 MHz for spurious signals. Spurious signals should
be -60 dBc maximum. Record test data in table 5-3.
5-5.1.5 Input Return Loss Test
9. Reset and turn on amplifier module. Read and record the S
11
return loss measurement on
network analyzer. Input return loss should be –16 dB maximum. Record test data in table
5-3.
