Comparison of Time Domain Scans and Stepped Frequency Scans in EMI Test Receivers

Achieve a significant reduction in measurement times without affecting accuracy

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.

From this white paper, the reader will:

    • Learn how an FFT-based test receiver operates
    • See a performance comparison of speed and accuracy
    • Find out how to choose the right measurement time
