Tests and Adjustments
Preliminary Checks
• A repeated failure in any of the ranges of the attenuator check indicates a faulty step
attenuator.
— If the Port 1 check fails, the A25 step attenuator may be faulty.
— If the Port 2 check fails, the A26 step attenuator may be faulty.
Refer to "Removing and Replacing the A36 and A37 60-dB Step Attenuators (Option
UNL)" on page
• If all ranges of the attenuator check fail, suspect a loose connection on the step
attenuator control cable.
— If the Port 1 check fails, check the A25 step attenuator cable.
— If the Port 2 check fails, check the A26 step attenuator cable.
