Abstract

In this paper an advanced ultra-fast broadband time-domain EMI (TDEMI) measurement system based on a multi-level analog-to-digital converter (ADC) is presented. The proposed multi-level quantization system is compared with a single ADC system. The multi-level system is modelled and investigated experimentally in the 30-1000 MHz frequency range. Measurement results and the results of computer simulations are compared. Utilizing of digital signal processing for spectral estimation of EMI signals simultaneously with multilevel quantization allows to reduce the measurement time by a factor of 50 in comparison to a conventional EMI receiver
