When measuring the conducted interference emission, the interference variables emitted by a device via the connected cables are determined
The main causes for the emission of conducted interference are, for example, fast switching processes, ground loops, grounding problems and the antenna effect of supply lines. Depending on the area of application of the device, there are various limits for the emitted interference that must be checked.
Testing the conducted interference emission, e.g. in accordance with the basic standard DIN EN 55016-2-1 / CISPR 16-2-1
or basic automotive standards EN 55025 / CISP 25 and ISO 7637-2 serves as verification,
that the interference emitted by the device under test does not affect other devices.
Potential sources of interference can be identified by measuring the conducted interference emission.
and eliminated by using interference suppression filters or decoupling capacitors.
The tests are carried out both for transient interference emissions in the time domain (e.g. due to switching on/off processes) and for continuous interference emissions.
Other test methods (e.g. DIN EN (IEC) 61000-3-2, 61000-3-3, 61000-3-11, 61000-3-12) measure and evaluate the reaction of the test object on the supply network.

Extracts from the relevant standards
- DIN EN 5516-2-1 / CISPR 16-2-1 – Interference voltage
This part of CISPR 16 is a basic standard and describes the measurement of conducted disturbances in the frequency range from 9 kHz to 30 MHz. A network simulation forms an agreed reference impedance to which the RF disturbance variables are measured. - DIN EN 55025 / CISPR 25 und ISO 7637-2 – Interference voltage
Bei elektrischen Bauteilen ist die Spannung relevant, die der Prüfling auf den Versorgungsleitungen abgibt. The interference voltage is measured with the aid of vehicle electrical system simulations. Transient interference voltages caused by switching on and off processes are generated and measured using an electronic switch, for example. - DIN EN 55016-2-1 / CISPR 16-2-1 – Interference current
This part of CISPR 16 is a basic standard and describes the measurement of conducted interference currents in the frequency range from 9 kHz to 30 MHz or more. This measurement method is used, for example, if it is not possible to insert a network simulation for interference voltage measurement. - DIN EN 55025 / CISPR 25 – Interference current
The interference currents emitted by electrical components on the supply lines are relevant here. The interference currents are measured using current clamps in different measuring arrangements.
