The Keysight M8290A optical modulation analyzer and high-speed digitizer test solution is a flexible platform for up to 400G coherent devices and transmitter test. It incorporates a 92 GSa/s modular optical modulation analyzer and a 92 GSa/s four-channel electrical digitizer. The platform has an additional arbitrary waveform generator module up to 92 GSa/s to add to the same AXIe chassis. This setup is a compact and flexible test solution and easily integrates with software for integrated, coherent receiver (ICR) and coherent optical device (COD) module characterization.

  • Compact and flexible AXIe modular form factor
  • Maximum symbol rate at 74 Gbaud 
  • Sample rate at 83 to 92 GSa/s 
  • Maximum record length at 512 k samples 
  • Eight-bit ADC resolution


  • Coherent optical transmitter testing
  • Coherent receiver ICR testing
  • Coherent optical transmit and receive devices
