(9) Set function generator for a sine wave, 100 kHz, 1 mVp-p, 50 output. Slowly
increase function generator amplitude until TI displays a stable indication at approximately
100 kHz. If function generator amplitude exceeds 71 mVp-p; perform b below.
(10) Repeat step (9) above at 5 kHz and 10 Hz.
(11) Press TI keys 2, 0, SHIFT, STORE, SF, SHIFT, SF.
(12) Disconnect function generator from TI.
b. Adjustments
(1) Disconnect signal or function generator from TI INPUT B and press TI
RESET/CONTINUE key.
(2) Adjust R150 (fig. 1) fully ccw.
(3) Adjust R193 (fig. 1) to its mid-point.
(4) Press TI RESOLUTION
key until TI displays 000.
(5) Connect signal generator rear panel EXT REF INPUT to TI rear panel 10MHz
STD. OUTPUT.
(6) Connect signal generator RF output to TI INPUT B.
(7) Set signal generator RF output to 100 MHz and output level to 3 mV rms.
NOTE
Adjustment of R193 in (8) below will cause random displays to
occur on both sides of the correct setting.
(8) Adjust R193 (fig. 1) to obtain a stable 100.0 0.1 E6 TI indication with GATE
and INPUT B TRIG LEDs flashing.
(9) Disconnect signal generator from TI INPUT B.
(10) If TI does not indicate 100.0 0.1 E-6 without GATE LED flashing, repeat step
(6) above through (10).
(11) Press TI RESET/CONTINUE key.
key until display indicates 00000000.
(12) Press TI RESOLUTION
(13) Reconnect signal generator RF output to TI INPUT B.
(14) Set signal generator amplitude to 13 mV.
(15) Slowly adjust R150 (fig. 1) cw until TI display just becomes unstable.
(16) Slowly adjust R150 (fig. 1) ccw until TI display stabilizes and indicates
100.000000 .000001.
(17) Set signal generator amplitude to 7 mV.
(18) If TI GATE LED is flashing; repeat step (14) above through (18).
