RF cable's impedance and return loss are the main indexs that most people interested. Along with the unceasing development of test technologies, the test methods changes with it as well. The measurement methods for impedance and return loss are frequency domain and time domain. The frequency domain method may use the network analyzer or other sweep frequency instrumentations, and time domain method can use the TDR or pulse generators that combining with broadband sampling oscilloscopes.
