Abstract

Time-domain EMI Measurements allow to reduce the measurement time by a factor of 2000 in comparison to measurements in frequency domain. EMI receivers use a preselective filter to obtain a high spurious free dynamic range for stationary and transient signals. In this paper a novel method is introduced that enhances the spurious free dynamic range of the Time-domain EMI Measurement System. This allows the application of the system to measurements of spurious emissions of communication systems. A correction of nonlinearities of the ADCs is performed to suppress harmonics and intermodulation products. Several measurements have benn performed with different sampling rates of the ADCs to remove spurious signals from the spectrum. A spurious free dynamic range of 90 dB has been achieved for a stationary signal in the frequency range 30 MHz - 1 GHz. The spurious free dynamic range for stationary signals has been investigated and compared with results obtained by an EMI receiver.
