47. Fast Time Domain Sweeps ,HP 8591EM Option 101 and Option 301

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

The CAL OUT signal is used to compare the amplitude level of a normal sweep time (20 ms) to a fast sweep time (18 ms) using the marker delta function.

A synthesizer/level generator is used to amplitude modulate a 500 MHz, CW signal from another signal generator. The EMC analyzer demodulates this signal in zero span to display the response in the time domain. The marker delta frequency function on the EMC analyzer is used to read out the sweep time.

There are no related adjustment procedures for this performance test.
