Every EMC immunity test begins with one essential question: what level of field strength is required for your device to be fully compliant? Achieving accurate EMC field measurement is the foundation for ensuring that your test results truly represent your product’s performance. The next challenge is to get the field strength up to this level. This sounds easy but a lot of factors must be considered. For example, the dimensions of your GTEM cell or test chamber, the lengths of your RF power cables, the performance of your amplifiers and the gain of your antennas. Either way getting that value right is critical.
Risk of over-testing or under-testing
Generating too little field strength (under-testing) can mask weaknesses in your design, while generating too much can exaggerate failures that would not occur when having the field on the correct level. Accurate measurement ensures that your test results reflect your product’s true performance, not errors in setup. Precise field strength measurement reduce false failures and prevent wasted development efforts.
RadiSense® field probes from Raditeq are designed for accurate EMC field measurement. They measure electric field strength with extremely high accuracy, due to its low anisotropy across its entire frequency range. Whether you are testing in accordance to EN 61000-4-3, ISO 11451-2, MIlStd. 461 RS103 or using reverberation chambers, RadiSense® ensures fast, accurate and traceable results.
In EMC testing, precision is key. The closer your measurements reflect reality, the more confidently you can prove compliance and ensure a reliable product.
