Measurements

Average

Average is the sum of the levels of the waveform samples divided by the
number of samples.

measurement interval.
The Full Screen measurement interval variation measures the value on all
displayed data points.
The N Cycles measurement interval variation measures the value on an
integral number of periods of the displayed signal. If less than three edges
are present, the measurement shows "No edges".
The X cursors show what interval of the waveform is being measured.

DC RMS

DC RMS is the root- mean- square value of the waveform over one or more
full periods.
RMS (dc) =
