Traditionally emission measurements are carried out in frequency domain using pre- and final scans. Time-domain EMI measurement systems allow to reduce the scan time by orders of magnitude, enabling novel test methods. In this paper the measurement uncertainty for intermittent signals during pre-and final scans is investigated. The effect of the dwell time on the measurement accuracy in the peak and...
Traditionally emission measurements are performed in frequency domain by EMI-Receivers. The drawback of EMI receivers is the long measurement time, up to several hours for a single frequency scan. By emission measurements in time-domain and simulation of several thousand EMI receivers by a digital signal processing unit the measurement time can be reduced by several orders of magnitude. In this paper...
Time-domain EMI Measurement Systems allow to reduce the measurement time by several orders of magnitude. In this paper novel test procedures for radiated emission measurements based on a realtime time-domain emi measurement system are presented. Those test procedures take advantage of the parallel calculation of the spectrum at several thousand frequency bins. By a full maximization procedure full...
