  • Abstract
    FFT-based measuring instruments can be used for EMI compliance measurements in accordance with Amendment 1 to 3rd Edition of CISPR 16-1-1 if this standard is referenced in the product standard. The use is motivated by reducing the scan time by several orders of magnitude. A part of this time saving can be used for applying longer measurement times in order to reliably detect narrowband intermittent signals or isolated pulses. For precise and reproducible measurements the use of preselection filters is highly recommended.
