DIN EN 3475-812:2025-07

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 812: Return loss (VSWR); German and English version prEN 3475-812:2025 / Note: Date of issue 2025-05-30*Intended as replacement for DIN EN 3475-812 (2010-09).

Fecha edición:	2025-07-01 En Vigor
Idiomas disponibles:	Alemán, Inglés
Resumen:	This standard 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 applicable together with EN 3475-100 and EN 50289-1-11.
