  • Automated testing to regulatory Limit Lines with user-selected margins
  • Amplitude correction for antennas, LISNs, cables, preamps
  • Built-in report generation


  • Perform precompliance radiated and conducted emissions measurements
  • Diagnose non-compliant emissions with extensive spectrum analysis capability
  • Analyze emissions vs. time using Strip Chart functionality
  • Perform precompliance “Click” measurements


  • Display log frequency span and three simultaneous detectors
  • Reduce measurement time with built-in signal list and Monitor Spectrum capabilities
  • Speed data collection with optional Time Domain Scan capability

Other features

The N6141A EMI measurement application is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. This application transforms the X-Series signal analyzers into a powerful EMI precompliance and diagnostic solution, providing easy-to-use data collection and analysis tools which facilitate rapid time-to-market for new designs.

EMI measurements

  • Observe single frequency emissions performance using up to three meters that are updated simultaneously
  • Collect emissions suspect lists rapidly using built-in testing to limit lines
  • Analyze suspect emission characteristics in the spectrum analyzer mode
