Pre-conformance spurious emissions testing from Verkotan

Pre-conformance spurious emissions testing is important during the R&D stage to ensure that the spurious emissions of a device are acceptable and under control and that the device complies with international and regional limits set by the FCC, RED and ISED. Ensuring that the spurious emissions of a device are under control can save time and money in the EMC testing stage.

Pre-conformance spurious emissions testing

Spurious emissions test is a mandatory test for radio devices that transmit radio signals. Spurious signals are unwanted signals that a device under test might transmit. There are strict international and regional limits to spurious emissions set by the FCC, RED and ISED. Spurious emissions test is a part of the EMC testing process. In fact, it is one of the most common tests to be failed on the way to EMC certification. Ensuring that the spurious emissions of a device are under control by performing pre-conformance spurious emissions testing, saves time and money in the EMC testing stage.

Spurious signals can cause connection problems to other wireless devices and are often caused by transmitted radio signals or digital clock signals. It is recommended to perform spurious emissions test in the R&D stage to ensure that the spurious emissions of a device are under control.

Why pre-conformance spurious emissions testing?

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

How is the testing done?

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.

Equipment to be tested

Verkotan can test devices that include 2G, 3G, 4G and 5G radios. Verkotan can also produce a comprehensive 3D visual analysis of the spurious emissions test results.

Verkotan can perform spurious emission tests for example to
