The new Keysight 81606A Tunable Laser Source has been designed to reach a new accuracy level and to increase test efficiency. 

It accelerates swept-wavelength tests with sub-picometer repeatability and best-in-class accuracy, even in the new two-way sweep mode at 200 nm/s speed.

15 dB more dynamic range through +12 dBm output power with the product family’s lowest spontaneous emission, enables the validation of extremely deep filters.

A 4-fold improved absolute accuracy and 40 times faster sweeps at the same accuracy became possible through the real-time tracking speed and high resolution of the novel wavelength reference unit and its built-in gas cell.
