The theory of operation, along with the usual block diagrams, schematics, etc, for the OPT 021 for the 5328B is in the 5328B service manual.  It may be the same, or at least close enough to, the 5328A.  It's worth a try.  You can download the 5328B manual here:

Has anyone seen a sevice manual or a schematic for the HP-5328A Option
21 DVM.  I have the 5328A service manual but it says the DVM Option 21
is covered in a separate manual.  Without a schematic debugging could
take a long time as the DVM is spread over three plug-in boards.
