HP 5334a service manual

Does anyone know where I could find a download of a HP 5334a service manual?

The manual is for the B model but the differences are probably nothing to worry about.

Thanks tekfan.

The schematics for the 5334b version share similar components designations to the 5334a. Although the B revision integrated the
channel C 1.3GHz prescaler on the main PCB, while on version A, this was on a separate PCB option that connected through a 10pin SIL header.

This is what I've determined about that connector thus far, but the functions of pins 3 and 8 escape me.

1. GND
2. GND
3. ??
4. +15
5. prescaled CLK to mainboard
6. +5
7. -5.2
8. ??
9. GND
10. GND

I have a 5334A counter and the paper service manual for it. I don't have a practical way to scan it, but I can try to help with specific info you need. Here is a schematic of the channel C option.
