:MEASure:VRMS
Syntax 1
:MEASure:VRMS [<chan>]
Description 1
Measures the amplitude effective value (Vrms) of the specified source channel.
Syntax 2
:MEASure:VRMS? [<chan>]
Description 2
Measures and queries the amplitude effective value (Vrms) of the specified source channel. The unit is
related to the current amplitude unit of the specified source channel.

Remarks
Amplitude effective value (Vrms): indicates the root mean square value of the waveform amplitude
within the current measurement range (refer to the :MEASure:AREA command).
Before making measurements, turn on the channels to be measured.
When the math operation type is FFT (refer to the :CALCulate:MODE command), <chan> cannot be
set to "MATH".
When [<chan>] is omitted, the command, by default, applies to the currently set measurement source
(refer to the :MEASure:SOURce command).
Return Format
The query returns the measurement results in scientific notation. When the measurement results are
invalid, the query returns 9.9e37.
