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 tuned to several di￿erent frequencies and the amplitude of the second and third harmonics relative to the fundamental are measured at each frequency.

There are no related adjustment procedures for this performance veri￿cation test.

Equipment Required

Spectrum analyzer, microwave

Cable, Type N, 62 cm (24 in)

Cable, BNC, 23 cm (9 in)

Adapter, Type N (m) to BNC (f)

Procedure

Note

It is only necessary to perform Step 1 if more than two hours

 

have elapsed since a front-panel calibration of the microwave

 

spectrum analyzer was performed.

 

The microwave spectrum analyzer should be allowed to warm

 

up for at least 30 minutes before proceeding.

 

 

1.Perform a front-panel calibration of the microwave spectrum analyzer by performing the following steps:

Note that the following steps are for an HP 8566A/B microwave spectrum analyzer, the steps may be di￿erent if you are using another microwave spectrum analyzer.

a. Connect a BNC cable between the CAL OUTPUT and the RF INPUT.
