44. Residual Responses , HP 8591EM

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

The EMC analyzer input is terminated and the EMC analyzer is swept from 150 kHz to 1 MHz. Then the EMC analyzer is swept in 10 MHz spans throughout the 1 MHz to 1.8 GHz range. Any responses above the speci￿cation are noted.

There are no related adjustment procedures for this performance test.
