Performance Verification Tests
11. Sweep Time Accuracy
11. Sweep Time Accuracy
This test uses a function generator to amplitude-modulate a 500 MHz
CW signal from another signal generator. The analyzer demodulates
this signal in zero span to display the response in the time domain. The
marker ∆ function on the analyzer is used to read out the sweep time
accuracy.
If the analyzer is equipped with Option AYX, also perform “Fast Time
Domain Amplitude Accuracy” in addition to this procedure.
There are no related adjustment procedures for this performance test.
