Re: 2465B error code


 

The error indicates a problem with the CT (Counter-Timer) option.
My 2465B, 2445B, 2467B Options Service Manual (070-6864-01), available as a PDF scan from Artek Manuals (no affiliation) describes your error in table 5.4 (Maintenance Chapter), last item on page 5.4
The message indicates an error with the trigger path tests and tells you to check the associated circuits.

You'll need to get a service manual if only to find your way around the circuits.
