a. Performance Check
(1) Connect function generator Function Outputs Unbalanced to TI INPUT A
using 50 Ω feedthrough termination (omit termination for option H60).
(2) Set function generator for a sine wave, 10 kHz, 1 mVp-p, 50 Ω output. Slowly
increase function generator amplitude until TI indication is stable at approximately
10 kHz. If function generator amplitude exceeds 71 mVp-p (42 mVp-p for AN/USM-459 and
5328AF096), perform b (1) through (4) below (b (5) through (10) below for AN/USM-459 and
5328AF096).
(3) Repeat (2) above at 10 Hz, 1 kHz, 100 kHz, and 1 MHz.
(4) Set TI CHANNEL A DC/AC switch to AC.
