(12) Press TI RESOLUTION ↑ key until display indicates 00000000.
(13) Reconnect signal generator OUTPUT RF 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 E6.
(17) Set signal generator amplitude to 7 mV.
(18) If TI GATE LED is flashing; repeat (14) above through (18).
11. Channel C Sensitivity
a. Performance Check
(1) Press TI RESET/CONTINUE key.
(2) Connect signal generator OUTPUT RF to TI INPUT C 50Ω.
(3) Press FUNCTION ↑ or ↓ key to select INPUT C.
(4) Set signal generator frequency to 1300 MHz and amplitude to 1 mV. Slowly
increase signal generator amplitude until TI displays a stable indication at approximately
1300 MHz. If signal generator amplitude is not less than 75 mV; perform b below.
(5) Repeat technique of (4) above at 1000 MHz, 500 MHz, 100 MHz and 40 MHz. If
signal generator amplitude is not less than 15 mV; perform b below.
(6) Disconnect signal generator from TI.
b. Adjustments
(1) Connect signal generator rear panel EXT REF INPUT to TI rear panel 10MHz
STD. OUTPUT.
(3) Set signal generator frequency to 1000 MHz and amplitude to 8 mV.
(4) Slowly adjust R27 (fig. 1) ccw to obtain a stable TI indication of 1000.00000 .00001
E6 with GATE LED flashing.
