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

Yeah that's the guy who says it's "IBM 3740 format", and the lists 40

Re: Plug in surge question
Don't use a Variac on modern equipment with switchmode power supplies.
They are constant power so draw more current with lower voltage.
