Count Accuracy Performance Test
The test verifies the count accuracy of the built-in frequency counter. The PSA performs
the Marker Count function by pausing between sweeps, tuning the center frequency to the
marker frequency, setting the span to zero hertz, and then counting the frequency of the
signal long enough to achieve a valid reading.
A synthesized source is used to supply the signal at a known frequency. The PSA 10 MHz
frequency reference is connected to the source to lock it to the DUT.
