17.Resolution (IF) Bandwidth A ccuracy,HP 8590 EM-Series

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

The output of a synthesizer/level generator is connected to the input of the EMC analyzer. Measurements are performed in zero span to reduce the measurement uncertainty.

The frequency of the synthesizer/level generator is set to the center of the bandwidth-￿lter response. The synthesizer output is then reduced in amplitude by either 3 dB or 6 dB to determine the reference point. A marker reference is set and the synthesizer output is increased to its previous level.

The frequency of the synthesizer is reduced then recorded when the resulting marker amplitude matches the previously set marker reference. The synthesizer frequency is increased so that it is tuned on the opposite point on the skirt of the ￿lter response. The frequency is once again recorded and the di￿erence between the two frequencies is compared to the speci￿cation.
