Rapid method for measurement of cable surface transfer impedance

A new simple method for the in situ measurement of the surface transfer impedance of coaxial cables is described. The method is based on injecting a disturbing current onto the outside of the test cable and measuring the corresponding voltage induced on the center conductor. It is shown to produce reliable results at frequencies up to 150 MHz with the use of a 1-m length of cable. ©1996 John Wiley & Sons, Inc.
