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 used similar boards from a third party supplier and they just dropped straight in. As a quick first check I would suggest monitoring the output from the MB510, either on the 030 board or at the ribbon cable, just to confirm that the board is dividing as expected. There is an HP Service Note 53132A-04A that discusses the firmware requirements for updating which also might be worth checking just in case that's an issue.

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.
