(11) Disconnect signal generator from TI.
(12) Set TI FREQ RESOLUTION, N switch to 1Hz, 106 and CHANNEL B DC/AC
switch to AC.
(13) Repeat (3) through (11) above substituting 20 Hz for 10 Hz and 0.000002 for
0.000001 in table 4.
b. Adjustments
(1) Connect signal generator OUTPUT RF to TI INPUT B using 50 Ω feedthrough
termination (omit termination for option H60).
(2) Set signal generator for a 40 MHz, 25 mV output.
NOTE
Do not adjust sensitivity below 10 mV.
indication (R).
(4) Slowly decrease signal generator output and repeat (3) above.
(5) Connect TI CHANNEL B MARKER OUTPUT to oscilloscope Vertical 1 input
using a 50 Ω feedthrough termination.
(6) Set oscilloscope channel 1 for DC input coupling, 1MΩ input, 500mV/div
amplitude and 10 s/div sweep.
(7) Set oscilloscope triggering for positive slope, auto level, channel 1 source
and DC coupling.
(8) Connect function generator Function Outputs Unbalanced to TI INPUT B
using 50 Ω feedthrough termination.
(9) Set function generator for a sine wave, 10 kHz, 42 mVp-p, 50 Ω output.
(10) Adjust oscilloscope controls as necessary to view waveform. Adjust A12R28
(11) Adjust A12R54 (fig. 1) for a stable TI 0.00100 indication (R).
a. Performance Check
(1) Connect signal generator OUTPUT RF to TI CHANNEL C input.
