Estimated sweep time
1. Only available for the combined measurement mode selected under Measurement type.
2. The estimated sweep time is not equal to the estimated measurement time displayed in the
status bar during a measurement. The estimated measurement time includes additionally the
polarization time, the depolarization time and the selected noise suppression filter time.
