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.
