Test Description

A 50 MHz CW signal is applied to the Input of the analyzer. The amplitude of the source
and the analyzer's reference level are decreased in 10 dB steps. The analyzer marker
functions are used to measure the amplitude difference between steps. Reference Level
Accuracy is tested in both Log and Linear Scale Modes. Most of the error is contributed
from the output attenuator inaccuracy in the synthesized sweeper and not the analyzer.
