This standard BS EN 3475-812:2009 Aerospace series. Cables, electrical, aircraft use. Test methods is classified in these ICS categories:
49.060 Aerospace electric equipment and systems
This standard specifies methods for measuring return loss (VSWR), in the required frequency bandwith of coaxial cables with characteristic impedance. The return loss is used for quantifying the level of the reflected signal due to the irregularity of the characteristic impedance of the cable. It is intended to be used together with EN 3475-100.
