Parameters
1.
Oscilloscopes
with
bandwidth
less
than
100MHz
can
auto
measure
the
following
voltage
parameters:
Max:
The
voltage
value
between
the
highest
point
of
a
waveform
and
GND.
Min:
The
voltage
value
between
the
lowest
point
of
a
waveform
and
GND.
High:
The
voltage
value
between
the
top
of
a
waveform
and
GND.
Low:
The
voltage
value
between
the
bottom
of
a
waveform
and
GND.
Middle:
Half
of
the
summed
voltage
value
for
“High”
and
“Low”.
Pk
‐
Pk:
The
voltage
value
between
the
highest
and
the
lowest
points
of
a
waveform.
Ampl:
The
voltage
value
between
the
top
and
the
bottom
of
a
waveform.
Mean:
Mean
amplitude
of
the
waveform
being
displayed
by
the
screen.
CycMean:
Mean
amplitude
for
signal
within
a
cycle.
RMS:
RMS
of
the
waveform
being
displayed.
CycRMS:
Namely
the
RMS,
in
another
word,
it
is
the
DC
voltage
value
that
may
generate
an
amount
of
