Abstract:
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 heterodyne EMI Receiver. The system's ultra-low noise figure of 6-8 dB over the complete freque...    »
