The

the

Once

This
mode
adopts
super
sampling
technology
that
averages
the
proximal
points
of
waveform
being
sampled.
In
this
way,
it
reduces
the
random
noise
in
the
input
signal
and
displays
an
even
more
smooth
waveform
on
the
screen.
It
is
commonly
applied
in
such
circumstance
where
the
sampling
rate
of
digital
converter
is
higher
than
the
saving
rate
of
sampling
memory.
Notes:
The
average
methods
used
by
“average”
and
“high
resolution”
modes
are
different
as
the
former
is
an
average
of
repeat
sampling,
while
the
latter
is
an
average
of
single
sampling.
