(12) Connect function generator output to TI front panel BNC input using a 50
eedthrough termination.
(13) Set function generator frequency to 10 Hz and amplitude to 1 mVp-p. Slowly
increase function generator amplitude until TI displays a stable indication of applied
frequency. Function generator amplitude will not exceed 141 mVp-p.
(14) Set function generator amplitude to 141 mVp-p.
(15) Increment function generator frequency from 10 Hz to 10 MHz. If TI does not
display a stable indication at each frequency increment, perform b below.

(19) Increment signal generator frequency from 10 to 25 MHz. TI will display a
stable indication at each frequency increment.
b. Adjustments
(1) Set function generator frequency to 1 MHz and amplitude to 200 mVp-p.
(2) Decrease function generator amplitude while adjusting A3R8 (fig. 2) to a point
where TI no longer counts (R).
(3) Verify that sensitivity is at least 35 mVp-p.
19. Frequency and Sensitivity Check - 500 MHz to 18 GHz
a. Performance Check
CAUTION
Do not exceed +25 dBm peak of input power at the N type
connector (500 MHz to 18 GHz), SMA connector for model
5343A. Damage to the internal sampler may result.
