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: VNA Reference Impedance Renormalization
Good catch, Dave!? I'd kind of skimmed over the .pdf and then filed it for future reference myself.
I'd measured some boards probably 10-15 years ago with a 50 ohm VNA and was surprised to get

Microsoft requires you to buy a plugin to easily view them. It’s an Apple format. The free ones are unwieldy to use.

Hi!
Some pictures and a list of items would be appreciated.
I personally could imagine to want a 'grab bag' of a small quantity of
the individual items. You know, 'just in case'.
