What is BS EN 62037-4 - Passive RF and microwave devices, intermodulation level measurement about?
BS EN 62037 is a series on passive RF and microwave devices, intermodulation level measurement. coaxial cable is an electrical connector designed to work at radio frequencies in the multi-megahertz range. BS EN 62037-4 defines test fixtures and procedures recommended for measuring levels of passive intermodulation generated by coaxial cables. Two dynamic test methods and a static test method are defined.
All coaxial cables are subjected to the static and clamped cable loop dynamic test. Cables classified as flexible or semi-flexible are additionally subjected to the flexing tool dynamic test.
Who is BS EN 62037-4 - Passive RF and microwave devices, intermodulation level measurement for?
BS EN 62037-4 on passive RF and microwave devices, intermodulation level measurement is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 62037-4 - Passive RF and microwave devices, intermodulation level measurement?
RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. BS EN 62037-4 describes that intermodulation in long cables is measured using the reverse set-up because of the significant attenuation of these cables.
If the cable to be measured is long enough, i.e., with a one-way insertion loss of 10 dB or greater, it is required only to connector the end to be tested. Use connectors with known low IM performance relative to the DUT. Soldered joints are preferred. Similarly, if a termination is required, this is also of known low IM performance relative to the DUT. See IEC 62037-3 for additional information. Using BS EN 62037-4 you can define test fixtures and procedures recommended for measuring levels of passive intermodulation generated by coaxial cables.
