Aerospace series - Elements of electrical and optical connection - Test methods - Part 222: Insertion Loss (I.L.)

This standard specifies a measurement method of insertion loss, 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).

EN 2591-222:2007 (E) 3 Foreword This document (EN 2591-222:2007) has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.



EN 2591-222:2007 (E) 4 1 Scope This standard specifies a measurement method of insertion loss, 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). 2 Normative references The following referenced documents are indispensable for the application 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 2591-100, Aerospace series — Elements of electrical and optical connection — Test methods — Part 100: General. 3 Preparation of specimens The sampling shall include, for each specified cable, a minimum of two section of coaxial cable with connector in both ends. The first section called “Reference” is constituted as follow (see Figure 1):  (600 ± 5) mm of coaxial cable  1 male coaxial connector (SMA, N or TNC type …)  1 female coaxial connector (SMA, N or TNC type …)

EN 2591-222:2007 (E) 5 The coaxial connectors shall be selected to offer optimum performances for each used cable and measured frequency range. They must have a reflection coefficient better than 0,1 (− 20 dB) in the test frequency range. It is necessary to use the same type of connector on each section of cable. The second section called “Measure” (see Figure 2) is constituted by the same elements as “Reference Section”, the sample to be measured shall be installed in the middle of the section of the cable.
