Why is the determination of radiated emissions measurements and compliance with the limit values so important?
Due to the ever increasing frequencies in modern electronics, conductor paths are increasingly becoming possible antennas. The emitted radiated interference can lead to unwanted interference, which affect the properties of other electronic devices and systems.
The test of the radiated interference emission, e.g. according to the test standard DIN EN 55016-2-3 or CISPR 16-2-3 or in the automotive sector the basic standard DIN EN 55025 / CISPR 25 serves to prove that the interference radiation emitted by a device or vehicle component in a frequency range specified by a standard does not affect other devices.
The measurement of radiated emissions is also required as part of the type approval of ESA’s / EUB’s in accordance with UNECE Regulation No. 10 (R10).
Potential sources of interference can be identified and eliminated by measuring the radiated interference emission.

Extracts from the relevant standards
- DIN EN 55016-2-3 / CISPR 16-2-3 – High frequency fields
For electrical components, the quantity to be measured is, the maximum electric field strength emitted by the test object as a function of the horizontal and vertical polarization and at heights from 1m to 4m and circumferentially from 0° to 360°.
With AKUVIB, measurements are taken at a horizontal distance of 3 m from the test specimen, whereby the test specimen is rotated horizontally through all angles. To measure the electric field strength, the height of the antenna above the reflecting surface is varied. - MIL-STD-461 F / G RE101 – Magnetic fields
This standard is intended to limit low-frequency magnetic fields. This is intended to protect other systems that operate at very low frequencies. - DIN EN 55025 / CISPR 25 – High-frequency fields Automotive
In this measurement, the field strength is determined at a horizontal distance of 1 m from the device under test, whereby the test specimen together with the cable harness is placed on a table with a ground plane. To measure the electric field strength, the antenna is placed at different positions depending on the frequency. - Other automotive standards that require measurements of radiated disturbance emissions on components:
- BMW GS 95002-2, GS 95002-3, 95002-5
- MBN 10284-2, 10284-3, 10284-4
- Renault / Nissan 36-00-808
- PSA B 21 7110
- VW TL 81000
- Ford FMC 1278, EMC-CS-2029
- GM GMW 3097
