18、ntrolled Copy, (c) BSI4 1 Scope This standard specifies a test method of measuring the characteristic impedance of a couple of connectors, a couple of coaxial contacts. It shall be use together with EN 2591-100. 2 Normative references The following referenced documents are indispensable for the appl
19、ication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 4604-002, Aerospace series Cable, electrical, for signal transmission Part 002: General. 3 Preparation of specimens 3.1 Connectors Each contact shall be wired with the shortest p
21、ossible length of coaxial cable according to EN 4604-002, with the closest impedance to the product standard. The free end of one coaxial cable shall be connected to a load resistor with same value than the cable impedance. 3.2 Contacts Each contact shall be wired with the shortest possible length o
22、f coaxial cable according to EN 4604-002, with the closest impedance to the product standard. Then the contact shall be fitted in a dedicated connector as per EN 3155-002. The free end of one coaxial cable shall be connected to a load resistor with same value than the cable impedance. See Figure 1.
