a. Set measuring receiver LINE switches to ON position and allow 1 hour for

equipment to warm-up.

b. Prepare measuring receiver to measure RF power.

c. Connect TI to 115 V ac source and turn power on and allow sufficient warm-up time.

8. Insertion Loss and Rejection Test

a. Performance Check

(1) Connect POINT A (fig. 1) to the TI RF INPUT and POINT B (fig. 1) to TI RF

OUTPUT. Set signal generator RF OUTPUT on.

NOTE

Ignore any faults/errors on the TI when setting the TI to 00
