Count Accuracy Performance Test

This test verifies the count accuracy of the built-in frequency counter. To perform marker count, the analyzer pauses between sweeps, tunes the center frequency to the marker frequency, sets the span to 0 Hz, and counts the frequency of the signal long enough to achieve a valid reading.

A synthesized sweeper is used to supply signals of known frequencies. The 10 MHz reference for the sweeper is supplied by the DUT.
