Agilent / HP / Keysight 86146B

This Analyzer is a high performance benchtop optical spectrum analyzer with a filter mode that provides the flexibility to drop a single DWDM channel as tight as 12.5GHz spacing with fast tuning speed, low insertion loss, and highly repeatable wavelength accuracy.

The OSA uses a patented double pass monochromator design to simultaneously achieve high sensitivity and dynamic range with a fast sweep time.
