"Taking Time-Domain EMI Measurements According to International EMC Standards,"
by S. Braun and P. Russer
in Compliance Engineering Journal, vol. 23, no. 1, pp. 45ߝ54, March 2006.
For electromagnetic compatibility, radiation emission measurements are to date carried out in frequency domain in accordance with applicable emission measurement CISPR and ANSI standards, using a conventional heterodyne receiver. This paper discusses and summarizes the theory, setup, and algorithms in time domain, as well as the practical aspects of pre and full compliance radiation emission measurement system in real time resulting in comparison, a good many orders faster measurements using several sub-bands processing units for the frequency range up to 1 GHz. By making use of the deterministic and stochastic processes and fast Fourier transform based time frequency analysis, the digital signal processing is used for the statistical spectral estimation and detection, that provides same degree of accuracy and signal to noise ratio by the parallel emulation- of all required detector modes and auxiliary outputs, and better dynamic range with lower noise floor than with conventional EMC receivers and spectrum analyzers. This will considerably reduce the compliance test and development costs of electrical devices.
