Hi Jim:
I've seen a similar problem when one end of a ribbon cable connector is
soldered to the wrong side of a PCB.
Maybe you can unsolder a connector and install it on the other side?
Have Fun,

I think I may need to clarify my prior posting.
Both old and new Channel 3 boards work fine (and read correctly) in my older
53132A counter.
Both old and new Channel 3 boards fail to work properly in (and read 4x actual)
the newer 53132A counter.
So I think the problem is in the newer main 531
No, the suggestion makes perfect sense. A 12 GHz input board likely
has an internal prescaler with a division ratio that is 4 times that
of a 3 GHz input board, in order to have the main counter running at
the same internal frequency. For example, a 3 GHz input might divide
by 32 while a 12 GHz i

Many thanks for all the replies.
Nigel, thank you for the link. I did have this pdf, but was not reading it
correctly.
It has been suggested that perhaps the counter main board was "set up"
(modified) for a 12GHz channel 3. That would have required some mods to the
actual main board, but I a
Jim,
You were looking for a 0 Ohm resistor.
Sometimes HP did not, in fact, insert a 0 Ohm resistor component in later
revs of some PCBs. They just added the default 0 Ohmers in etch, between
two vias. Then, if someone wanted to open the link, the etch was cut. I
guess it saved a couple of pennies
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

Hi Jim
According to the schematic in the 53132A service manual and the datasheet
for the MB510 prescaler, the option 030 board is hard wired for a division
ratio of 1/128, and that's the lowest division ratio shown for that
prescaler.
I've not fitted one of the original HP boards but have
