682XXB/683XXB MM 5-35A11 FM PCB

Error 116 FM Loop Gain Check Failed

Description: The FM loop has failed or the loop gain is out of toler-

ance.

Step 1. Perform a preliminary calibration. (Refer to chapter 4 for the

calibration procedure.)

Step 2. Run self-test.

If error 116is not displayed, the problem is cleared.

If error 116is still displayed, go to step 3.

Step 3. Replace the A11PCB and run self-test again.

If error 116is not displayed, the problem is cleared.

If error 116is displayed, contact your local ANRITSU serv-

ice center for assistance.
