Sweep time
The minimum sweep time depends on the number of measurement points, the measurement
bandwidth, the delay time before each partial measurement and the number of partial measurements
required for each measurement point. The analyzer estimates this time, taking into account the current
measurement settings.
If the total sweep time entered via Channel - Stimulus - Stop is smaller than the estimated minimum
sweep time, the analyzer opens a dialog to adjust (increase) the stop time.
Trigger settings

active, the analyzer generates an error message:
To continue, click OK and select any other trigger source.
In Time sweep mode the Start, Center and Stop softkeys are inactive, still you can

partial measurement of a measurement point. The total number of measurement points is defined via
