The Agilent Keysight 86145B is a portable, high-performance optical spectrum analyzer designed for 50 GHz and wider Wavelength Division Multiplexing (WDM) systems. It delivers identical measurement capabilities to the benchtop Agilent 86142B but in a smaller footprint and lighter weight, featuring 10 pm wavelength accuracy, fast dual-sweep measurement speeds, and built-in WDM, DFB-LD, and EDFA test applications.
