Ultrawideband Time- and Frequency-Domain Characterization of EMC Facilities



David R. Novotny, Robert T. Johnk, Claude Weil, Seturnino Canales


We have developed a methodology to determine the quality of an EMC test facility using equipment generally available to RF testing services. By utilizing both the time- and frequency-domain, an accurate picture of the scattering and modal properties of the facility can be determined. This gives more information about the facility performance than a traditional scalar, frequency sweep of the facility. While the frequency information given from traditional Normalized Site Attunation (NSA) type measurements are available, this dual-domain method highlights the causes of the irregularties. This can help eliminate guesswork and focus remediation efforts to a facility that may be out of compliance.
