56.Non-Harmonic Spurious Outputs , HP 8591EM Option 010

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

The tracking generator output is connected to the EMC analyzer input and the tracking is adjusted at 300 MHz for a maximum signal level. The tracking generator output is then connected to the input of a microwave spectrum analyzer. The tracking generator is set to several di￿erent output frequencies.

For each output frequency, several sweeps are taken on the microwave spectrum analyzer over di￿erent frequency spans and the highest displayed spurious response is measured in each span. Responses at the fundamental frequency of the tracking generator output or their harmonics are ignored. The amplitude of the highest spurious response is recorded.

There are no related adjustments for this performance test.
