Aerospace series - Cables, electrical, aircraft use - Test methods - Part 812: Return loss (VSWR)
Abstract
This document specifies methods for measuring return loss respectively voltage standing wave ratio (VSWR), in the required frequency range of coaxial cables. The return loss is used for quantifying the level of the reflected signal due to an impedance mismatch between the cable and the reference impedance and due to structural variations of the impedance along the cable. It is intended to be used together with EN 3475 100 and EN 50289 1 11. NOTE In particular, correction procedures detailed in EN 50289 1 11:2016, Annex B are important to minimize negative effects of cable preparation in the purpose of high frequency range measurements.
