Description

N4391A Best in Test Image

The N4391A is a high end turn-key optical modulation analyzer for advanced research in single and multi-carrier 400 Gbit/s and 1Tbit/s complex modulated transmission systems. It is based on the latest Z-Series Keysight oscilloscopes, a 40 GHz dual polarization coherent receiver and optical modulation vector signal analysis software offering most flexible analysis tools and smart setup for easiest instrument setup.

Benefits

  • Highest confidence in test results through full calibrated turn-key solution
  • Widest range of modulation format offering
  • Based on world class Z-Series 4 channel Keysight oscilloscope

Features

  • Fully integrated in Vector Signal Analysis software with smart setup
  • Analysis software also available as PC stand-alone version
  • User configurable APSK and OFDM demodulator
  • Modulation-format transparent polarization alignment
  • Clearly structured measurement resultsaward_logo
  • Optical characterization results for each polarization plane separately
  • Optical summary results for complete signal
  • BER and Q factor separated for each polarization plane and overall signal
  • Freely configurable screen layout
  • Internal PMF switch to select internal or external local oscillator laser for best long term test results
  • Free selection and sequence of DSP algorithms
  • Various CD and PMD compensation and measurement algorithms
  • Integration of user DSP algorithm with the same freedom as Keysight algorithms
