:MEASure:VRMS
(see page 658)
Command Syntax
:MEASure:VRMS [<source>]
<source> ::= {CHANnel<n> | FUNCtion | MATH}
<n>::={1|2|3|4}forthefour channel oscilloscope models
<n> ::= {1 | 2} for the two channel oscilloscope models
The :MEASure:VRMS command installs a screen measurement and starts a
dc RMS value measurement. If the optional source parameter is specified,
the current source is modified.
Query Syntax
:MEASure:VRMS? [<source>]
The :MEASure:VRMS? query measures and outputs the dc RMS value of
the selected waveform. The dc RMS value is measured on an integral
number of periods of the displayed signal. If at least three edges are not
present, the oscilloscope computes the RMS value on all displayed data
points.
Return Format
<value><NL>
<value> ::= calculated dc RMS value in NR3 format
