(2) Adjust A1C11 (fig. 6) for 1000 Hz on frequency counter (R).
(3) Set RANGE switch to X10K.
(4) Readjust A1C11 (fig. 6) for 100 kHz on frequency counter.
(5) Repeat (1) through (4) above for best in-tolerance condition.
30. Sawtooth Output
a. Performance Check
(1) Connect oscilloscope to function generator CHANNEL A OUTPUT.
to X.01. If oscilloscope does not display sawtooth waveform with amplitude of 15 V or
greater over entire frequency range of TI, perform b (1) through (3) and (5) below.
NOTE
Adjust AMPLITUDE control fully cw. Return to ccw position
after check.
(3) Set TI SAWTOOTH slide switch to - (negative) and repeat (2) above.
(4) Remove connection from CHANNEL A and connect to CHANNEL B OUTPUT.
NOTE
TI CHANNEL B slide switch must be in SAWTOOTH
position.
(5) Repeat technique of (2) and (3) above for CHANNEL B OUTPUT. If
oscilloscope does not display sawtooth with amplitude of 15 V or greater, perform b (1), (2),
(4), and (5) below.
b. Adjustments
(1) Connect jumper between TP2 and CIRCUIT GND (fig. 6).
(2) Connect multimeter between TI upper center terminal of SAWTOOTH slide
switch and circuit ground.
(3) Adjust A3R15 (fig. 6) until multimeter indicates +10 V (R).
(4) Adjust A3R38 (fig. 6) until multimeter indicates +10 V (R).
(5) Remove jumper connected in (1) above.
31. Frequency Response
a. Performance Check
(1) Connect oscilloscope to function generator CHANNEL A OUTPUT.
Set AMPLITUDE control fully cw.
