DC RMS
DC RMS is the root-mean-square value of the waveform over one or more full
periods.
Where x
i
= value at
i
th point being measured, n = number of points in
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 the interval of the waveform being measured.
AC RMS
AC RMS is the root-mean-square value of the waveform, with the DC component
removed. It is useful, for example, for measuring power supply noise.
The N Cycles measurement interval 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 the interval of the waveform being measured.
The Full Screen (Std Deviation) measurement interval variation is an RMS
measurement across the full screen with the DC component removed. It shows the
standard deviation of the displayed voltage values.
The standard deviation of a measurement is the amount that a measurement
varies from the mean value. The Mean value of a measurement is the statistical
average of the measurement.
