EMC: Radiated Emissions

Measuring radiated emissions from devices is accomplished using a certain set of equipment based on specific applications. Whether looking at near field or far field, different types of antennas and measuring devices will be used. Depending on compliance, pre-compliance, or simple troubleshooting, anything from an EMI test receiver to a simple spectrum analyzer can be used with antennas or near field probes to measure emissions. Using this test equipment setup allows for understanding where device emissions are located. GTEM/TEM-cells are useful for isolating the device under test and acting as an antenna to measure emissions. Pre-amplifiers may be necessary in certain cases when looking for very small signal emissions. Test standards such as CISPR, MIL-STD, and IEC are met in full compliance when renting from Advanced Test Equipment Rentals.
