(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.

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)

(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.
