Re: 2465B CTT options board faults

I just finished remotely helping a friend with his scope,toggle quoted messageShow quoted text
and was getting my confidence pretty well shaken when two
trigger hybrids both failed. It took a third, this time
from our friend in Greece, to fix the problem.
As I said earlier, there is a booming business in selling
almost good trigger hybrids on ebay.
The CTT and the automatic frequency measurement both use
a function in the trigger hybrid that isn't used by any other
A perfectly performing scope can have a trigger hybrid that
won't measure frequency, or work with the CTT.
I wish I could say that just replace this part or tweak that
pot, and your hybrid will come back to life, but I haven't
figured out what that part is, or where that pot resides...
Dear Chuck: Many thanks
