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.
