:MEASure:VRMS?
Syntax
:MEASure:VRMS? <chan>
Description
Query the RMS value of the amplitude of the selected waveform.
Parameter
Name Type Range Default
<chan> Discrete {CHANnel1|CHANnel2} CHANnel2
Explanation
The unit depends on the unit of the source channel (refer to
the
:CHANnel<n>:UNITs command).
Return Format
The query returns the measurement result in scientific notation.
Example
:MEASure:VRMS? CHANnel1
The query returns 1.385354e+00.
You can use the following commands to query the statistic maximum, minimum,
current value, average and standard deviation of the RMS values of the amplitude of
the selected waveform. Sending the following commands will enable the statistic
function automatically.
 :MEASure:VRMS:SMAXimum?
 :MEASure:VRMS:SMINimum?
 :MEASure:VRMS:SCURrent?
 :MEASure:VRMS:SAVerage?
