STORAGE DISPLAYS
STORAGE
1.
Obtain a normal display
of
the signal to
be
measured
(see Normal Sweep Display
in
the Basic Oscilloscope
Displays section
of
this manual).
2.
Set the STORAGE LEVEL and VIEW TIME controls
to
NORM. Set the SAVE switch button out. Select either
VAR
PERS
or
FAST mode.
NOTE
a.
In general,
better
results are
obtained
using the
VAR
PERS
mode
for sweep speeds slower than
100 µs/division.
b.
When using the
combination
of
FAST storage
and
B DL Y'D
horizontal
display, set A TRIG HOLDOFF
control
to
BENDS
A
for
maximum
display repetition
rate.
3.
Push the ERASE button.
Allow
a few seconds for the
storage and
trigger
circuits
to
automatically provide a
display.
4.
Set the INTENSITY control
for
adequate
display
brightness. Set
the
STORAGE LEVEL
control
for
optimum
display (depends on the amplitude and speed of the signal
to be viewed). Set the VIEW TIME
control
for
the desired
display retention (persistence) in the VAR PERS mode
or
for
the time between erase cycles in the FAST mode.
5.
Push the ERASE button. The display is erased,
except in the SAVE mode, and the storage and
trigger
circuits are reset.
SAVE STORAGE
1.
Obtain a Storage Display using steps 1
through
4.
2.
Immediately after the event is ·stored, push in the
SAVE button, providing a longer viewing time. The SAVE
INTENS
control
adjusts the display brightness. Increasing
the display brightness decreases the viewing time.
Pushing the SAVE button, after the event is stored, can
be
delayed
up
to
several seconds (depending on the VIEW
TIME setting), this reduces maximum viewing time.
Maximum viewing time occurs when the SAVE INTENS
control
is
set
fully
counterclockwise, advancing the
control
only
long enough
to
view the display.
3.
Erase
is
disabled in the SAVE mode.
