Fast EMC Emission Measurements in Time Domain 2004-01-1705
EMC Emission Measurements are usually carried out in frequency domain with measuring receivers and spectrum analyzers in frequency domain. The advantage is the sensitivity of the measurement by pre-selecting the input signal. The time consumption of such a frequency scan is significant high.
Modern oscilloscopes cover the needed frequency range and with additional signal processing the sensitivity can be significant improved. Therefore modern time domain EMC emission techniques are a time and cost effective alternative to traditional frequency range measurement. Further more the “real” signal is being monitored which allows the design engineer to trace the source of the emission much better than with frequency range methods.
