Name：Keysight 86122A

Features: Wavelength scan in less than 0.5sec Wavelength accuracy: ± 0.3 pm High Laser Input power: 10dBm (18dBm - Safe Input level) Advanced built-in measurement applications (Drift, OSNR, Data Logging, FP Laser Characterization) Built-in HeNe laser wavelength standard Benefits: The fast wavelength scan allows you to double the speed of characterizing optical devices versus wavelength. The wavelength accuracy gives you the certainty of accurate channel characterization in dense WDM systems, to detect channel's wavelength shift and crosstalk between adjacent channels. Enables you to test transmitter without additional connections and instruments (e.g. attenuator). The built-in applications allow smart stand-alone test stations, which reduces footprint requirements and costly test procedure development. The built-in HeNe guarantees an accurate absolute wavelength measurement real-time determined against the standard anytime and ensures accurate and reproducible experimental results.
