18. Gain Compression Test
30. Connect cable to power sensor and adjust output level of
synthesizer for a power meter indication of -5.00 ho.02
dB.
Reconnect cable to spectrum analyzer input.
31. Change [REFERENCE LEVEL) to -5
dBm.
Record the MKR A amplitude:
dB.
32. Subtract the value recorded in step 9 from the value obtained
in step 31 to find the gain compression:
dB.
The
result should be
>-
1.0
dB
(less than 1
dB
compression).
33. Disconnect cable from the spectrum analyzer RF INPUT. Connect
the spectrum analyzer CAL OUTPUT to RF INPUT.
34. Press
