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.
