This standard BS EN 2591-221:2007 Aerospace series. Elements of electrical and optical connection. Test methods is classified in these ICS categories:
49.060 Aerospace electric equipment and systems
This standard specifies a measurement method of VSWR, in the required frequency bandwidth of coax contacts or connectors with characteristic impedance. It shall be used together with EN 2591-100. The measurement is carried out according to vectorial method using “S” parameters (see definition in Annex A).
