20、E RF AND MICROWAVE DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 2: Measurement of passive intermodulation in coaxial cable assemblies 1 Scope This part of IEC 62037 defines a procedure to measure levels of passive intermodulation generated by a coaxial cable assembly. This test method is applicab
21、le to jumper cables, i.e. cable assemblies intended to provide interface flexibility between rigid devices. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the editi

23、IM Passive intermodulation 4 Test set-up Set-up 1 and set-up 2 are applicable in this PIM-test. Either set-up 1 (reverse method, see 6.2.2 of IEC 62037-1:2012), or set-up 2 (forward method, see 6.2.3 of IEC 62037-1:2012), may be used for cable assemblies, provided that the attenuation of the assembl
24、y is not greater than 1 dB. For higher attenuation, the reverse method shall be used. The connector under test should be clamped and mechanically secured to prevent its movement during the test. A describable and repeatable mechanical stress is applied to the DUT. This mechanical stress is defined b
25、y a distance d, between the end of the cable-entry (the last rigid mechanical point of the connector) and the point of the deflection, and circular movement around the cable axis with a radius r. This test shall be performed on each end independently. An example of a test set-up is shown in Figure 1
26、. The cable movement is depicted in Figure 2. The rotational radius (r) and distance (d) is defined in Table 1. The cable attachment to the termination should be supported.

The movement of the cable shall be carried out with a minimum of 3 cycles and a rate of (5 2) s per revolution. Torsion shall not be applied to the cable. It is recom
30、mended to rotate the cable clockwise. 5 Procedure The procedure is as follows: a) calibrate the set-up; b) connect the DUT to the set-up; c) read the PIM before applying mechanical stress; d) apply mechanical stress to the DUT according to Table 1; e) read the maximum PIM level while applying mechan
31、ical stress to the DUT; NOTE If using a spectrum analyser, it is helpful to use the “max-hold” function. f) stop the mechanical stress; g) read the PIM level after applying mechanical stress. 6 Report The report should include the following: a) radius; b) distance from the PIM tester; c) PIM levels
32、during rotation; d) PIM levels after rotation. _ BS EN 62037-2:2013This page deliberately left blankThis page deliberately left blankBSI is the independent national body responsible for preparing British Standards and other standards-related publications, information and services.
