Before going to a laboratory with a new prototype for EMC testing, it is advisable to perform pre-evaluation measurements.


In order to detect potential EMC problems beforehand, pre-evaluation instruments are used at CEMDAL. These instruments have limitations compared to the laboratory ones, however they are suited for finding problems before the prototype is taken to the laboratory, thus reducing the likelihood of having to go back to the laboratory several times.



The following measurements can be made: conducted emissions at 230V, radiated emissions -without a Faraday cage-, electrostatic discharge (ESD) in the air, EFT tests -rapid transients up to 2kV- and radiated immunity up to 12V/m with near-field probes. Following these measurements, a brief report is handed out to the customer. When the problems have been found, the report includes a list of basic solutions.
