In this work, a broadband Time-Domain EMI Measurement System with high sensitivity for measurements from 9 kHz to 18 GHz is presented. Combining ultra-fast analog-to-digital-conversion and real-time digital signal processing on a field-programmable-gate-array (FPGA) with ultra-broadband multi-stage down-conversion, scan times can be reduced by several orders of magnitude in comparison to a traditional...
Time-domain electromagnetic interference (EMI) measurement systems allow measurement time to be reduced by several orders of magnitude. In this paper, a novel real-time operating time-domain EMI measurement system is presented. By the use of several analog-to-digital converters, the dynamic range requested by international electromagnetic compatibility (EMC) standards is achieved. A real-time operating...
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...
