The EMI-specific measurement bandwidths and CISPR detectors provided by the K54 option allow the use of standard EMI measurement methods to measure emission levels. Limit lines allow simple identification of critical levels and related frequencies. The K54 option provides a library of limit lines for common product standards – so they do not have to be created individually – as well as functions for in-depth signal analysis.
The K54 option supports automated analysis of large frequency ranges. This is particularly helpful when using detectors with long measuring times, such as a quasi-peak detector (measuring time ≥ 1 s). The K54 option sweeps the user-defined frequency range with a fast detector, usually a peak detector, and only measures automatically detected critical frequencies with a slow detector. The results are compiled in a table for a quick and easy overview.
The results can also be exported in a customizable layout with the trace and other details in a PDF or Microsoft Word document.
