Notes:
If
intend
to
observe
signal
envelopes
and
avoid
signal
aliasing,
please
use
peak
detection
mode.
If
time
base
is
slower
than
100ms/div,
and
hence
need
to
adopt
deep
memory,
the
trigger
mode
has
to
be
set
to
normal
or
single.
Deep
memory
and
fast
sampling
can
not
be
opened
at
the
same
time.
2.5.4
Fast
Sampling
Fast
sampling
allows
users
to
capture
waveform
rapidly.
With
this
function,
the
unit
can
capture
150,000
waveforms
per
second
(150,000
wfms/s),
making
it
possible
for
users
to
see
burrs
and
other
accidental
transient
signal
within
a
few
seconds.
