Taking the R&S ESR EMI test receiver as an example, this paper looks at a CISPR 16-1-1-compliant test instrument with time domain scanning capabilities. The paper compares the measurement speed and level measurement accuracy of a conventional stepped frequency scan versus an advanced FFT-based time domain scan. It also contains guidance on making optimum use of time domain scans.
