7. Noise Sidebands

A 1 GHz CW signal is applied to the input of the analyzer. The marker
functions are used to measure the amplitude of the carrier and the
noise level at 10 kHz, 20 kHz, and 30 kHz above and below the carrier.
The 100 kHz offset from the carrier is also tested on Agilent E4401B
and E4411B analyzers. For all other analyzers, the 100 kHz offset from
the carrier is tested in performance test 8. Noise Sidebands - Wide
Offsets: Agilent E4402B, E4404B, E4405B and E4407B.
There are no related adjustment procedures for this performance test.
