Impedance measurement method of coaxial cables

QHow to measure the impedance of coaxial cables using an LCR meter


Connect the Hpot and Hcur to the shield of the coaxial cable, and connect Lpt and Lcur to the core wire.

Impedance is measured by opening the one side to obtain [Zo] and shorting the other side to obtain [Zs].

Then, the impedance characteristics is calculated with the formula Z=√(ZoZs).
