To
use
the
Integrate
function,
first
obtain
a
triggered,
well-
defined
display.
Then
press
INTEGRATE
button
in
(a
fraction
of
a
second
to
several
seconds
is
reasonable).
If
all
portions
of
the
display
are
not
properly
stored,
repeat
the
integrate
period
with
higher
trace
intensity.
Example:
Set
VOLTS/DIV
switch
to
5
DIV
CAL
and
TIME/DIV
switch
to
.1
ms.
Set
INTENSITY
control
for
normal
display
of
square
wave.
Press
STORE
button
in,
then
erase
stored
display.
Reduce
intensity
so
that
the
display
is
just
visible
(erase
display
each
time
intensity
is
adjusted).
Press
INTEGRATE
button
in
and
note
that
the
stored
trace
is
brightened.
Low
trace
intensity
and
long
integration
periods
produce
optimum
resolution
on
jitter-free
signals.
However,
if
inte
gration
period
is
too
long,
the
stored
image
may
broaden
and
obscure
the
desired
display.
Use
of
integrate
function
in
AUTO
ERASE
mode
is
not
recommended.
CARE
OF
STORAGE
CRT
To
prolong
the
useful
life
of
the
storage
screen,
the
follow
ing
precautions
should
be
observed:
1.
Use
minimum
beam
intensity
required
to
produce
a
clear,
well-defined
display.
Care
must
be
exercised
in
the
degree
of
writing
beam
intensity
used,
particu
larly
when
using
slow
sweep
rates.
2.
Do
not
increase
beam
intensity
to
store
fast
chang
ing
portions
of
the
display.
See
Integrated
Fast-Rise
Waveforms.
3.
Avoid
repeated
use
of
the
same
area
of
the
screen.
4.
Do
not
leave
a
display
on
screen
(either
written
or
stored)
when
the
display
is
not
needed.
5.
Do
not
leave
the
STORE
button
in
when
the
STORAGE
mode
is
not
needed.
