Abstract

We have developed a methodology to determine the quality of an EMC test facility using equipment that may be generally available to RF testing services. By utilizing both, the time- and frequency-domains, 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 NSA type measurements are available, this dual-domain method highlights the causes of the irregularities. This can help eliminate guesswork and focus remediation efforts to a facility that may be out of compliance.
