a.Performance Check

(1) Connect TI SIGNAL to multimeter INPUT HI and LO using 50Ω feedthrough

termination.

(2)Press SIGNAL key off (option 002 not lit).

(3)Press presently active FUNCTION key to remove ac output and activate ENTRY DC OFFSET key (lit).

(4)Enter 5 VOLT using DATA keys and press AMPTD CAL key.

(5)Multimeter will indicate between 4.98 and 5.02 V dc.

(6)Enter -5 VOLT using DATA keys. Multimeter will indicate between -4.98 and -5.02 V dc.

(7)Repeat technique of (6) above using TI settings and multimeter indications listed in table 5.
