IEC EN 62037-2 Passive RF and Microwave Devices - Test for Coaxial Cable Assemblies

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62037-2 testing. This part of IEC EN 62037 defines a procedure for measuring passive intermodulation levels produced by a coaxial cable assembly.

This test method is applicable to jumpers, i.e. cable assemblies aimed at providing interface flexibility between rigid devices. It is also used to evaluate cable assemblies that are subject to movement during operation.

IEC EN 62037-2 is a standard that specifies the method for measuring the passive intermodulation (PIM) of coaxial cable assemblies used in RF and microwave communication systems.

Passive intermodulation is a phenomenon that can occur in RF and microwave systems when two or more signals of different frequencies are mixed in a non-linear device such as a coaxial cable, causing unwanted interference and distortion.

Some key points of the standard are:

• The standard applies to coaxial cable assemblies operating in the 0,05 GHz to 40 GHz frequency range;
• The measurement setup requires a test signal generator, a PIM analyzer, a directional coupler, and a terminating load;
• The test setup should be designed to eliminate any external source of PIM, such as loose connectors, corroded contacts, or metal objects nearby;
• PIM measurement is performed by injecting two test signals into the cable assembly and measuring the resulting third order intermodulation products produced by the cable assembly;
• The PIM level is expressed in dBc (decibels relative to carrier power) and is typically measured at a specific frequency and power level;
• The standard provides guidelines for the measurement procedure, including calibration of test equipment, selection of test frequencies and power levels, and interpretation of measurement results.

In general, the standard aims to provide reliable and accurate measurement of PIM in coaxial cable assemblies used in RF and microwave communication systems.
