Spurious emissions testing

Devices with integrated wireless technologies are liable to produce unwanted radio signals, so-called “spurious emissions”,  which tend to disturb other radio transmitters or even operator networks. For this reason, not only mobile phones but also short range devices and M2M products need to be tested for spurious emissions, which have to be within specified limits. Spurious emissions tests are required by regulatory bodies and industry committees such as the 3GPP and ETSI.

7layers has anechoic chambers available from several manufacturers, which can be used for R&D purposes or for certification and regulatory testing.

Mobile phones and in particular modern smart phones include a growing number of complex technologies. Cellular modules, Bluetooth or other wireless modules as well as integrated antennas, cameras, touch screens etc. must all work seamlessly together. 7layers offers radiated tests in free-space conditions during the R&D process to help achieve a fault-free design and a first-time pass for type approval and certification. For such purposes we use the InterLab Shielded Enclosure, which covers a multitude of test purposes, in this case spurious emissions testing. The Interlab Shielded Enclosure is ideally suited to a number of R&D test applications and is also available for manufacturers in-house test laboratories.
