Charactistic impedance testing
WebImpedance can be measured using a network analyzer, a laboratory Time Domain Reflectometer (TDR) or a controlled impedance test system that employs TDR techniques. An engineer with practice using controlled impedance test systems will run the impedance test to ensure high-quality results. WebAug 30, 2024 · The maximum charging voltage applied was 4 kV DC. The pulse traveled from the switch to the PEA test cell through a coaxial cable (RG213) of 50 Ω characteristic impedance. The coax cable was 100 m long to electrically decouple the switch from the test cell due to the propagation time and the pulse duration. The pulse had a 300 ns duration.
