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.
