Frequency Readout Accuracy Performance Test

The test verifies the accuracy of a displayed frequency relative to either the start frequency or the center frequency of the sweep. It is not necessary that the start/center frequency be accurately known. It must, however, be the same as the frequency supplied by the external source. This is accomplished by locking the source and DUT references thus eliminating the frequency reference term.

With the references locked, the test is done in several spans to check all modes of the synthesizer circuitry.
