an amplitude between 5 V and 20 V to the EXT BLANK
connector (rear panel). An example of this application is
the use of an accurate frequency, applied to the Z axis to
serve as timing information on an uncalibrated horizontal
sweep. However, the blanking frequency must be time re 
lated to the displayed waveform to produce a stable display.
HOW TO STORE A DISPLAY
a. Turn INTENSITY control fully counterclockwise and
press STORE button in. Note background light level, then
press ERASE button. Notice that the normal storage back 
ground light level is present on the storage screen.
b. Turn INTENSITY control slowly clockwise to produce
a display of normal intensity, then return the INTENSITY
control fully counterclockwise. Notice a stored display of
moderate brightness.
c. Press ERASE button and note that the crt display can be
erased.
d. Set STORE button to the out (non-store) position. Set
triggering and intensity for a stable display of normal bright 
ness.
e. Set the time base for single-sweep operation and press
STORE button in. Then press ERASE button.
@
f. Apply a single-sweep trace by pressing RESET button.
Note a stored display on the storage area. If the display is
not stored, increase the intensity (INTENSITY control
clockwise) and repeat the check.
g. Press AUTO ERASE button in. Note that the sweep is
displayed on the crt and further sweeps are locked out until
the stored display is erased.
h. Slowly rotate VIEWING TIME control throughout its
range and note that the control varies the time that the dis 
play remains stored before automatic erase.
i. Turn VIEWING TIME control fully clockwise. As soon as
the display is automatically erased, and another trace is stor 
ed, press ERASE button. Note that the display is erased and
other sweeps are locked out during the period selected by the
VIEWING TIME control. Release AUTO ERASE and STORE
buttons.
j. Set TIME/DIV switch to 1 µs and SWEEP MAG switch to
X10 and turn INTENSITY control fully clockwise.
k. Position the rising portion of the waveform within the
graticule area. Readjust INTENSITY control so that the
trace is just visible. Press STORE button in, then press
ERASE button. Note normal storage mode background
light on crt.
