EM TEST EFT 500Nx Series Test Equipment EFT 500N 4.1. Specification of the test parameters As per IEC 61000-4-4 the EFT pulses are specified as follows: Definition of a single pulses Definition of a complete burst on a 50 load on a 1000 ...
EM TEST EFT 500Nx Series 4.3. Coupling decoupling network The decoupling part of the coupling network has to: - filter the interference pulses in the direction to the power supply; - protect other systems that are connected to the same power supply and - realize a high impedance of the power supply, e.g.
EM TEST EFT 500Nx Series 4.4. Burst Test Setup - The test generator and the coupling network should be connected to the reference ground plane (acc. to high frequency requirements). - The equipment under test must be isolated from the reference ground plane. The distance should be 10cm.
To avoid such disturbances in the following paragraphs some information is given to which the operator has to take care: - EM TEST generators are tested with the maximum test level. If no damage has been occurred the equipment must be seen as immune.

EM TEST equipment. EM TEST doesn’t know each customer’s Quality Assurance Policy nor do we know how often the equipment is used and what kinds of tests are performed during the life cycle of test equipment. Only the customer knows all the details and therefore the customer needs to specify the calibration interval for his test equipment.
