TB 9-6625-2217-35
(8) Adjust R192 (fig. 1) to obtain a stable 100.0 0.1 E6 TI indication with GATE
and INPUT A TRIG LEDs flashing.
(9) Disconnect signal generator from TI INPUT A.
(10) If TI does not indicate 100.0 0.1 E6 without GATE LED flashing; repeat (6)
above through (10).
(11) Press TI RESET/CONTINUE key.
(12) Press TI RESOLUTION ↑ key until display indicates 00000000.
(13) Reconnect signal generator OUTPUT RF to TI INPUT A.
(14) Set signal generator amplitude to 13 mV.
(15) Slowly adjust R149 (fig. 1) cw until TI display just becomes unstable.
(16) Slowly adjust R149 (fig. 1) ccw until TI display stabilizes and indicates
100.000000 .000001 E6.
(17) Set signal generator amplitude to 7 mV.
(18) If TI GATE LED is flashing; repeat (14) above through (18).
10. Channel B Sensitivity
a. Performance Check
(1) Press TI INPUT B 50Ω/1MΩ key to select 50Ω (LED ON).
(2) Press TI keys 2, 1, SHIFT, STORE, SF, SHIFT, SF.
(3) Connect signal generator OUTPUT RF to TI INPUT B.
increase signal generator amplitude until TI displays a stable indication at approximately
100 MHz. If signal generator amplitude exceeds 25 mV, perform b below.
(5) Repeat (4) above at 10 MHz .
(6) Disconnect TI from signal generator.
(7) Connect TI INPUT B to function generator Function Outputs Unbalanced.
