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: 8594E input attenuator issue?
The through readings will vary with the value of the attenuation, but the to-ground readings should all be close to 50 Ohms with a 50 Ohm termination in place, as you said you did. I took a quick look

Re: 8594E input attenuator issue?
50-ohm termination is needed to get the correct attenuation but for measuring resistances it is not needed. From your earlier measurements it looks like: PAD2 is 20dB section PAD3 is 40dB section PAD4
