Communication cables. Specifications for test methods - Electrical test methods. Characteristic impedance, input impedance, return loss Ingestion-build-264231 corrosion-resistant steel1 Scope This part of EN 50289 details the test methods to determine characteristic impedance, input impedance and return loss of cables used in analogue and digital communication systems. It is to be read in conjunction with EN 5028911, which contains essential provisions for its application.
