:MEASure:VRMS
(see page 1138)
Command Syntax
:MEASure:VRMS [<interval>][,][<type>][,][<source>]
<interval> ::= {CYCLe | DISPlay}
<type> ::= {AC | DC}
<source> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r>}
<n> ::= 1-2 or 1-4 (# of analog channels) in NR1 format
<r> ::= 1-2 in NR1 format
The :MEASure:VRMS command installs a screen measurement and starts
an RMS value measurement. If the optional source parameter is specified,
the current source is modified.
The <interval> option lets you specify the measurement interval: either an
integral number of cycles, or the full screen. If <interval> is not specified,
DISPlay is implied.
The <type> option lets you choose between a DC RMS measurement and
an AC RMS measurement. If <type> is not specified, DC is implied.
Query Syntax
:MEASure:VRMS? [<interval>][,][<type>][,][<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

This command is not available if the source is FFT (Fast Fourier Transform).
