Set to Screen
Resets the cursors to their initial positions. This is helpful if the cursors have disap-
peared from the display or need to be moved for a larger distance.

14.5.1 Ripple
The " Ripple" analysis measures the ripple of the device output. In this measurement
the peak-to peak extremes of the output DC signal are of interest. The measurement
also includes the AC-RMS of the output DC signal, that is calculated as a standard der-
ivation.
14.5.1.1 Ripple results
The results of "Ripple" measurements are:
●
The voltage waveform
●
Numeric measurement results
Also, for each measurement result you can enable a statistic evaluation of the mea-
surement results. It returns the current, minimum and maximum measurement values,
the average and standard deviation, and the number of measured waveforms.
The numeric measurement results are defined as follows:
