Spurious emissions testing

Pre-conformance spurious emissions test helps to determine if a device is ready for the market entry and make sure that the device passes the spurious emissions test of the EMC testing process. With our pre-conformance testing, device manufacturers can be sure that their device’s spurious emissions comply with the limits set by different international and regional authorities.

Spurious signals can cause connection problems to other wireless devices and are often caused by transmitted radio signals or digital clock signals. Verkotan can perform spurious emissions tests already in the research and development stage to ensure that the spurious emissions of a device are under control.

The testing can be performed over-the-air in the frequency range of 400 MHz¬-44.5 GHz. Spurious emissions testing is performed in an anechoic Over-the-Air, OTA test chamber from the measurement distance of 1 to 3 meters by measuring the spurious emissions from all the sides of the device. After this the average amount of unwanted signals is counted and the final result will show if the device’s spurious emissions are within the limits. Other option to perform the testing is conducted testing, which can also be done up to 44,5GHz.
