In EMI testing, success depends on tools that can help you do more in less time—today and tomorrow. That's why we created the Keysight N9038B MXE EMI receiver, a standards-compliant diagnostic signal analyzer built on an upgradeable platform. In the lab and on the bench, it provides the accuracy, repeatability, and reliability you need to test with confidence. Equip your team with the N9038B MXE EMI receiver and keep the test queue flowing.

  • Perform EMI tests with a standard-compliant receiver: CISPR 16-1-1:2019, MIL-STD-461G, ANSI C63.2, and FCC
  • Reduce overall test time with time domain scanning enabled by fast Fourier transform (FFT) scans
  • Simplify measurement setup with the new, larger capacitive multi-touch screen and the Keysight X-Series signal analyzer menu structure optimized for touch user interface (UI)
  • Get enhanced diagnostics using spectrum and real-time analysis, strip chart, markers, and spectrogram
  • Evaluate emissions and identify suspect signals through the front panel or remotely with software
  • Migrate easily to the new platform with built-in code compatibility
