Further checking the service manual indicates that the main board treats
pins 9 and 10 of the ribbon cable as CH3code1 and CH3 code2 respectively so
perhaps it's using these as identifiers and it might be worth checking that
those signals are as expected. The prescaler board schematic shows 9 as
being connected to +12V and 10 to ground.
If you don't have access to the component level service manual let me know
and I'll send you a copy.

I hope this is not too OT.
I have acquired a 3.0GHz original Channel 3 board for my Agilent 53132A
counter. When installed, it reads four times (4x) the actual frequency.
I'm wondering if anyone has any experience with such an installation and
can
point me to some setup item or zero ohm resistor I'm supposed to install.
All that the manual says is to have it done by the factory. That will cost
me more than the board itself. Many thanks.
