I have an Agilent Impedance Analyzer. I'm current measuring two cables cables and trying to come up with a model that has vales per unit length. The cable lengths are 3 meters each. Then I can just multiple the values to get whatever distance I want.
The model:
So my plan to get R & L was to the ends of the cables to each other and measure Rs & Ls at the open side. Is this correct? Then R & L would be equal to half of Rs & Ls.
My real trouble is getting C between the cables. Anyone can help me? I thought to get C was to have both ends open and measure Cp from one side. But I was getting negative capacitance. Should I have both sides open and measure Cs?
Thanks in advance.
