The Keysight 86146B is a grating-based optical spectrum analyzer. The OSA uses a patented double-pass monochromator design to simultaneously achieve high sensitivity and dynamic range with a fast sweep time. This is key for characterizing DWDM components, broadband passive components, but also active optical components like narrowband sources (DFBs), wideband sources (FPs) and optical amplifier (EDFA, Raman amplifiers and SOAs).

Keysight's 86146B is a high performance benchtop optical spectrum analyzer with a filter mode that provides the flexibility to drop a single DWDM channel with fast-tuning speed, low-insertion loss, and highly repeatable wavelength accuracy.

Another application of the filter mode is to measure time-resolved chirp (TRC). Using the filter with a 86100C DCA, chirp measurements can be made on lasers.
