It shall be used together with EN 2591-100. 2 Normative references The following referenced documents are indispensable for t
18、he 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.
19、 3 Preparation of specimens The mating connector pair to be tested shall be assembled as shown on Figure 2 and tested as shown on Figure 1. Detail of Test assembly shall conform to Figure 3.

This test set-up between 500 MHz and 11 GH
23、z shall have a dynamic range from 20 dBm to 100 dBm. Using an additional RF source amplifier (e.g. 20 dB), increase total dynamic range. The shorting plunger is adjusted to produce a maximum reading in the detector with the triaxial assembly inserted. 5 Method The insertion loss caused by the insert
24、ion of the triaxial assembly adjusted as shown in a measure of total leakage of the mated connector pair both at its interface as well as the clamping points at both cable ends. The short circuit position is adjusted to assure that adequately low impedance appears behind the equivalent leakage gener
25、ator. The characteristic impedance of the outer coaxial line of the triaxial system, which is formed with the inner conductor, should be matched to the detector, 50 coaxial circuits are generally desired for convenience. 6 Results The leakage power ratio is defined as the ratio of the power detected
26、 to a detector at the output of the triaxial unit to the power flowing through the internal flowing power (also through a 50 load). The relative leakage is the ratio: 1221IEZ = where E2is equivalent leakage voltage in external line; I1is the current flowing in internal line. The value must be under
27、the requirement given in the product standard. The insertion loss caused by the insertion of the triaxial assembly adjusted as shown is a measure of the total leakage of the mated connector pair both at its interface as well as at the clamping points to both cables.
