9. System-Related Sidebands
A 500 MHz CW signal is applied to the input of the analyzer. The
marker functions are used to measure the amplitude of the carrier and
the amplitude of any system-related sidebands more than 30 kHz away
from the carrier. System-related sidebands are any internally generated
sidebands related to the line, power supply or local oscillator.
There are no related adjustment procedures for this performance test.
