Vrms - HP 54501A Programming Reference Manual

VRMS
VRMS
command/query
The :MEASURE:VRMS
command
places the instrument in the
continuous measurement
mode and starts
a
Vrms measurement.
The
VRMS
query
measures and outputs the
RMS
voltage of
the selected
waveform. The
RMS
voltage
is computed using the data available on the
display.
Note
This
RMS
measurement
is
an
AC RMS
measurement. This
means that the average value
of
the
waveform
is
subtracted
from
each data point before
RMS
is
computed.
Command Syntax:
:MEASure:VRMS
Example: OUTPUT 707;":MEAS:VRMS"
Query Syntax:
:MEASure:VRMS?
Returned Format: [:MEASure:VRMS]
<
value

Where:
<
value

=
rms voltage of displayed points (exponential
-
NR3 format)
Example: DIM Vrm$[50]
OUTPUT 707;":MEASURE:VRMS?"
ENTER 707;Vrm$
PRINT Vrm$
