Re: E4401B No 50MHZ Cal signal

Re: Type of coax for Impedance Analyzer Test Fixtures
The data is in the impedance handbook. It is coax. I think its a polyethylene dielectric. Its not obvious where the 1 m is measured from. I do have a couple of original test leads / fixtures so can

RG-174A/U shows as 50 ohms 102 pF/m That's pretty darn close!

Type of coax for Impedance Analyzer Test Fixtures
Does anyone have any idea what kind of coax is used for the 16048A, example below, or other test fixtures. HP say not to substitute. They are in various colours. Are they 50 ohm or just shielded wire?
