EMI compliance testing – from stepped scan to wideband time domain scan

Emission testing according to CISPR standards involve the most stringent requirements to EMI test receivers on the detection of intermittent interference. Every product standard benefits from the wideband time domain scan not only by the increased speed and flexibility, but also from extended measurement times that increase the probability of intercept for sporadic interference. With up to 970 MHz the EMI test receiver R&S^®ESW offers an unmatched wide FFT measurement bandwidth processed in real-time that enables extensive analysis and debugging, showing wide and detailed spectrogram plots without missing any pulses in time. The webinar presents practical examples to show the advantages of modern wideband FFT based time domain scan EMI receivers testing over classical stepped scan receivers or spectrum analyzers.
