The Keysight 11980A is a Mach-Zehnder interferometer of fixed delay. Used with a Keysight 71400 series or Keysight 83810B lightwave signal analyzer, it allows you to measure chirp and frequency modulation (FM) on DFB lasers. Traditional measurements of laser linewidth on single-line lasers can also be made.
