(8) Adjust R511 (fig. 1) so that display just triggers on positive peak of signal (R).
(9) Set TI TRIGGER SLOPE switch to
and TI TRIGGER LEVEL knob to
fully ccw position.
(10) Adjust R512 (fig. 1) so that display just triggers on negative peak of signal (R).
(11) Set TI TRIGGER MODE switch to NORM.
(12) Ensure TI TRIG'D indicator is illuminated when a stable display is present and
is not illuminated when a stable display is not present.
(13) Reduce outputs to minimum and disconnect equipment setup.
a. Performance Check
(1) Connect TI PROBE ADJUST to TI CH 1 OR X input.
(2) Set TI SEC/DIV switch to .5 ms, CH 1 VOLTS/DIV switch to .1 and variable
control for 5 divisions of vertical display (do not change setting).
(3) Disconnect TI PROBE ADJUST from TI CH 1 OR X input.
(4) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI CH 1 OR
X input.
(5) Set oscilloscope calibrator for a CH 1 VOLTAGE mode output of 500 mV at 1
kHz.
(6) Adjust TI TRIGGER LEVEL and POSITION controls, as necessary, to view
(7) Rotate oscilloscope calibrator knob located below EDIT FIELD key for 5
divisions of vertical display.
(8) Oscilloscope calibrator err display will indicate within 20%.
(9) Reduce outputs to minimum and disconnect equipment setup.
(10) If necessary, rotate TI CH 1 VOLTS/DIV CAL fully cw to detent.
b. Adjustments None
NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check.
(1) Connect digital multimeter low lead to TI TP934 (fig. 1) and multimeter hi lead
to TI TP952 (fig. 1). If digital multimeter does not indicate between 4.2 and 4.4 V dc,
perform b (1) below.
