N4L are the only IEC61000 EMC test system manufacturer in the world* with an on site UKAS ISO17025 calibration laboratory offering accreditation to IEC61000-3-2, IEC61000-3-3, IEC61000-4-7 and IEC61000-4-15. Calibration and trace-ability are a vital aspect of any EMC test solution and the coverage provided through N4L’s UKAS Laboratory is comprehensive. N4L’s IEC61000-4-15 calibration procedure is particularly noteworthy as it covers the entire test protocol detailed in Annex C of IEC61000-4-15. It is commonplace for specific parameters within IEC61000-4-15 (d parameters are frequently omitted from calibration procedures) to remain untested during typical flicker calibration due to the difficulty in providing trace-ability for such measurements. All tests within the test protocol of Annex C are included within the scope of accreditation and calibration procedures at N4L.
IECSoft is an integral component of the EMC test package, integrating the various hardware components and displaying the data in a clear manner. As an example of IECSoft’s flexibility, the user is able to send comprehensive test data to external customers or colleagues within the design department. This is useful as design engineers are able to replay Harmonics and Flicker tests in real time, allowing visualization of not only the results of the tests (in report form), but also determination of the devices performance throughout the test. An example of this may be that the final report of an IEC61000-3-2 test results in the EUT(Equipment under test) failing on Harmonic 5, IECSoft can replay the behavior of harmonic 5 throughout the test which can significantly reduce debugging time for the design engineer in the event of such a failed compliance test. In the past EMC test systems would only offer details of the harmonic failure levels in summary form, with an N4L EMC test system no such restrictions apply.
