I should also recommend you to fetch the HP3325B service manual from Agilent:


In there you will find a number of interesting additions which should help you
to understand and perform better trimming even of your 3325A.

I'll investigate how well my oppertunities to adjust my 3325B, but just looking
at it briefly it seems I could do most of it without much trouble.
