8.Frequency Span Readout A ccuracy, HP 8591EM

This performance veri￿cation test must be performed with the EMC analyzer set in the spectrum analyzer mode.

For testing each frequency span, two synthesized sources are used to provide two precisely-spaced signals. The EMC analyzer marker functions are used to measure this frequency di￿erence and the marker reading is compared to the speci￿cation.
