4.Frequency Readout and Marker Count A ccuracy, HP 8591EM and HP 8594EM

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

The frequency readout accuracy of the EMC analyzer is tested with an input signal of known frequency. By using the same frequency standard for the EMC analyzer and the synthesized sweeper, the frequency reference error is eliminated.

Equipment Required

Synthesized sweeper

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

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

Cable, BNC, 122 cm (48 in)

Cable, APC 3.5 mm (m) 91 cm (36 in)
