Vavg
Average
voltage
of
the first cycle
of the
displayed signal
is
measured.
If
a
complete cycle is not present the oscilloscope will average all
data
points.
Vrms
The nns voltage of the first cycle
of
the
displayed signal
is
measured.
If
a
complete cycle
is not present, the measurement will compute rms on all
data points.
