Measure:vrms - Agilent Technologies InfiniiVision 5000 Series Programmer's Manual

:MEASure:VRMS

Command Syntax
:MEASure:VRMS [<source>]
<source> ::= {CHANnel<n> | FUNCtion | MATH}
<n> ::= {1 | 2 | 3 | 4} for the four 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.
This command is not available if the source is FFT (Fast Fourier Transform).
N O T E
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
