(5) Repeat technique of (3) and (4) above, except do not readjust standardizer, for
VOLTS/DIV switch settings listed in table 18. If TI does not display optimum square
wave, perform appropriate adjustments listed in table 18.
(6) Press VERT MODE CH 2 and release CH 1 pushbuttons.
(7) Set oscilloscope calibrator for a CHAN 2, EDGE mode output of 25 mV at 1 kHz
and repeat technique of (3) through (5) above for CH 2 switch settings, except do not
readjust standardizer.
b. Adjustments. No further adjustments can be made.

40. Storage Acquisition Step Response
a. Performance Check
(1) Position controls as listed in (a) through (e) below:
VOLTS/DIV switches to 5m.
(a)
A AND B TIME/DIV AND DELAY TIME switches to .1 s.
(b)
STORAGE MODE NORM pushbutton pressed to ON.
(c)
DISPLAY RESPONSE pushbutton released to PULSE.
(d)

(2) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 2 to CH 2 input,
through 50 feedthrough termination.
(3) Set oscilloscope calibrator for a CHAN 2, EDGE mode output of 25 mV at 100
KHz and rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton for 5
divisions of display on TI. Press ENVELOPE STORAGE MODE pushbutton and then
press SAVE pushbutton.
(4) After envelope acquisition cycle completes, check that save waveform has less
than 1 minor division of overshoot on leading edge of waveform.
b. Adjustments. No adjustments can be made.
