6.Noise 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 noise level 10 kHz, 20 kHz, and 30 kHz above and below the carrier. The di￿erence between these two measurements is compared to speci￿cation after the result is normalized to 1 Hz.

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)

Procedure

This performance veri￿cation test consists of three parts:

Part 1: Noise Sideband Suppression at 10 kHz

Part 2: Noise Sideband Suppression at 20 kHz

Part 3: Noise Sideband Suppression at 30 kHz

Perform part 1 before performing part 2 or part 3 of this procedure.
