Procedure

It is only necessary to perform step 1 if more than 2 hours have elapsed since a front-panel calibration of the microwave spectrum analyzer has been 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 CAL OUTPUT and RF INPUT.

b.Select the 2 0 22 GHz band, then press INSTR PRESET, 4RECALL5, 8. Adjust AMPTD CAL for a marker amplitude reading of 010 dBm.

c.Press 4RECALL5, 9. Adjust FREQ ZERO for a maximum amplitude response.

d.Press SHIFT, FREQUENCY SPAN to start the 30 second internal error correction routine.

e.When the CALIBRATING! message disappears, press SHIFT, START FREQ to use the error correction factors just calculated.
