V rms.The
probe
operates
in
conjunction
with
the
instrument’s dc
voltage ranges, and
provides a dc output
that
is
calibrated to be
equivalent to
the rms
value of a
sinewave input.

6-27. The Model
85RF High
Frequency Probe
allows measurements over a
frequency
range of 100
kHz to 500
MHz from
.25V to 30V rms. It
operates in conjunction with the
DM
M's dc
voltage ranges,
and provides a
dc output that is calibrated
to be equivalent to
the rms
value of a
