CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

Re: Manuals for an HP3456B DMM?
Hi.
It's worth checking the DC power rails for the GPIB logic section.? It's possibly isolated from all the "measurement" analogue/digital stuff.
My old 3438A had "a lot" of 50Hz ripple on the GPIB
