g. Set oscilloscope for 2V / div and sweep to 2 s / div and enable TI output.

h. Adjust A1R410 (fig. 1) (amplitude) and A1R425 (fig. 1) (offset) for an output

amplitude of 16 V (8 divisions) symmetrical about 0 V. (R)

i. Set TI waveform to triangle. Adjust A1R227 (fig. 1) (amplitude) and A1R407 (fig. 1)

(balance) for an output amplitude of 16 V (8 divisions) symmetrical about 0 V. (R)

j. Set TI waveform to sine. Adjust A1R418 (fig. 1) (amplitude) and A1R402 (fig. 1)

(balance) for an output amplitude of 16 V (8 divisions) symmetrical about 0 V. Adjust

A1R409 (fig. 1) for optimum sine wave signal. (R)

k. Set TI as outlined in (1) through (3) below:

(1) Waveform to square.

(2) AMP to 1 V.

(3) OFS to 0 V.

l. Set oscilloscope to 200 mV / div. Turn A1R450 (fig. 1) fully ccw. Adjust A1R450 (fig.

1) and A1R416 (fig. 1) for an output amplitude of 1 V (5 divisions) symmetrical about

0 V. (R)

m. Set TI waveform to sine. Turn A1R445 (fig. 1) fully cw and then adjust it for an

output amplitude of 1 V (5 divisions). (R)

n. Set TI waveform to square and FRQ to 1 kHz. Set oscilloscope sweep to 200 s / div

and adjust A1R515 (fig. 1) for optimum squarewave. (R)

o. Set TI as outlined in (1) through (9) below:

(1) MODE (Input) to NORM.

(2) CTRL to off.

(3) Waveform to triangle.

(4) COMPL OUTPUT to off.

(5) DISABLE OUTPUT to On.

(6) FRQ to 10 MHz.

(7) DTY to 50%.

(8) AMP to 16 V.

(9) OFS to 0 V.

p. Set oscilloscope for 200 mV / div and sweep to 20 ns / div and enable TI output.

q. Adjust A1R535 (fig. 1) for a linear waveform. (R)

r. Set TI waveform to square and AMP to 16 V.

s. Set oscilloscope for 5 V / div and adjust A1C529 (fig. 1), in NORM and COMPL

modes, for <4% overshoot.

t. Set TI AMP to 1 V and oscilloscope to 200 mV / div. Adjust A1R535 (fig. 1), in NORM

and COMPL modes, for <4% overshoot.
