7.System Related Sidebands , HP 8590 EM-Series

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

A 500 MHz CW signal is applied to the input of the EMC analyzer. The marker functions are used to measure the amplitude of the carrier and the amplitude of any system related sidebands >30 kHz above and below the carrier. System related sidebands are any internally generated line related, power supply related or local oscillator related sidebands.

There are no related adjustment procedures for this performance test.

Equipment Required

Signal generator

Cable, Type N, 183 cm (72 in)

Additional Equipment for Option 026

Adapter, APC 3.5 (f) to Type N (f)
