(6) Connect signal generator RF output to TI INPUT B using 50
eedthrough termination.
(7) Set TI FREQ RESOLUTION, N switch to 10Hz.
(8) Set signal generator for frequencies in table 8. Slowly adjust signal generator
amplitude until TI indicates as listed. If adjusted signal generator amplitude exceeds
limits specified, perform b below.

(9) Disconnect signal generator from TI.
(10) Set TI FREQ RESOLUTION, N switch to 1Hz and CHANNEL B DC/AC
switch to AC.
(11) Connect function generator Function Outputs Unbalanced to TI INPUT B
using 50 feedthrough termination.
NOTE
In (12) through (16) below the TI indications are not critical but
should be stable. Only the channel B input sensitivity is being
checked.
(12) Set function generator for a sine wave, 50
output. Set function generator to
each frequency in table 9 and slowly adjust function generator amplitude until TI indicates
as listed. If adjusted function generator amplitude exceeds limits specified, perform b below.
