Impedance Matching and Smith Charts
uspas.fnal.govTypically, a coaxial cable will have a dielectric with relative dielectric constant er between the inner and outer conductor, where er = 1 for vacuum, and er = 2.29 for a typical polyethylene-insulated cable. The characteristic impedance of a coaxial cable with a dielectric is then and the propagation velocity of a wave is, where c is the speed ...

For TDR applications, the Tektronix oscilloscope uses a high-precision 3.5 mm air line connector as a stable impedance reference for the calculation of rho and ohms. Connector impedance is measured relative to an external, traceable, precision air line during module calibration.
