③、
Try
to
change
coupling
as
“high
frequency
reject”
or
“low
frequency
reject”
display
so
as
to
filter
those
high
or
low
frequency
noises
that
may
interfere
the
trigger.

①、
Check
if
the
“trigger
mode”
in
trigger
menu
has
been
set
to
“normal”
or
“single
time”
and
trigger
level
has
exceeded
the
waveform
scope.
If
so,
center
the
trigger
level
or
set
trigger

If
the
displaying
speed
gets
slower
once
the
average
sampling
mode
is
selected:
①、
If
averaging
times
is
above
32
times,
usually
the
displaying
speed
will
get
slower,
which
is
a
normal
phenomenon.
②、
Averaging
times
can
be
reduced.
5.
The
display
of
waveform
appears
in
stair
‐
step
shape:
①、
This
phenomenon
is
normal,
which
is
possibly
due
to
over
low
horizontal
time
base.
This
can
be
improved
by
enlarging
horizontal
time
base
to
improve
horizontal
resolution.
②、
It
is
possible
because
that
the
display
mode
has
been
set
to
vector.
The
connecting
line
between
sample
points
may
cause
it.
It
can
be
solved
by
setting
display
mode
to
point
display.
