Time Domain Scans Vs. Stepped Frequency Scans

Published by Rohde & Schwarz Inc.

Rohde & Schwarz launched with the R&S ESU the world's first commercial EMI test receiver capable of time domain scans. The EMI test receiver family R&S ESR does also support time domain scans and delivers even faster measurements.

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