EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62037-5 testing. IEC EN 62037-5 defines recommended test fixtures and procedures for measuring passive intermodulation levels produced by filters typically used in wireless communication systems. The aim is to describe proficiency and acceptance testing methods for filters for use in low intermodulation (low IM) applications.
Environmental and dynamic PIM testing, which may involve placing vibration or thermal stresses on filter assemblies while measuring simultaneously produced PIM, may not provide accurate or reproducible results. There are several important factors that affect the results of such PIM tests.
DUT/test system isolation, it is highly desirable to isolate any environmental and dynamic stresses applied to a DUT from the test system so that there are no measurable residual effects. This not only addresses the practical issues of test system reliability and maintenance, but also directly impacts the repeatability of measurement. That is, if a particular part of the test system needs to be replaced after a certain number of tries, the results of subsequent measurements may be skewed by the performance of the replaced part.
Measurement repeatability, it must be possible to repeat the results obtained from a given measurement with a certain precision. However, the inherent sensitivity of the PIM response may prevent the desired precision from being achieved.
Stress reproducibility, the particular stress applied to the DUT will be reproducible both between tests on the same DUT and between tests between different DUTs. However, in the experience of many, the reproducibility of a given stress will be much worse than that of certain PIM test results, so the standard for determining stress may not be unnecessarily strict.
