Perhaps the best methodology is to perform a number of pre-compliance tests on a product using a number of physical configurations. You can find the sources of your EMI and try to limit their contributions before the fully compliant testing even begins. While not fully providing fully compliant measurement data, pre-compliance testing can give you critical visibility into the design limitations of your design. This note covers pre-compliance measurements using a Rigol DSA-815 Spectrum Analyser with the optional EMI Measurement Kit (Part Number DSA800-EMI). This generally requires using a certified testing lab and special equipment that can be cost prohibitive for development and design tweaking.

This note will briefly cover some common practices for conducted emission testing early in the design phase and we will cover the radiated emissions in another note.ДЇor full qualification testing, a CISPR 16 qualified EMI Receiver and the proper setup must be used. Radiated emissions are those that are emitted into the area surrounding the EUT. Conducted emissions are those that propagate through the power line connecting the instrument (Equipment Under Test, or EUT here). In almost every case, these specifications contain limits on conducted and emitted radiation testing. This Electromagnetic Compatibility (EMC) testing is an integral part of product design and qualification for any electronics intended for sale within those markets.

In an effort to minimise these issues, countries have established standards and limits to products that are being sold within that market.

These effects can range from annoying glitches to rendering a product unusable. EMC Precompliance Testing: Conducted EmissionsД®lectromagnetic Interference (EMI) can cause undesirable effects on electronic products.
