Troubleshooting
In order to gain access to the front end components, remove the side chassis

Remove the Side Chassis
High Band #2 RF signal path utilizes a high band mixer internal to the A13
RF Front End Assembly for RF input frequencies from 13 GHz to 26.5 GHz.
Since all the control voltages and biasing were already fully tested, failures
from 13 GHz - 26.5 GHz will most likely be caused by the A13 RF Front End
Assembly. If the failure is amplitude related, proper adjustments such as
frequency response and the YTF Preselector adjust should be performed
first before changing the A13 RF Front End Assembly. Refer to
for details.
