Coaxial Cable Properties Introduction Coaxial cable is used for pulse transmission, where the wire and shield (separated by a dielectric) serve as a waveguide allowing small signals to be transmitted with minimal distortion. It has characteristic impedance (Z), capacitance (C), and inductance (L). The formulas for capacitance and inductance are: Cable Inductance. Next up is the inductance. You have to remove some of the insulation on the other side of the cable and short out the center pin to the shield. Then use the LCR Meter and measure the inductance at the open end of the cable. So now lets short out the other end of the cable and measure.
