Anritsu MS9001B1 Optical Spectrum Analyzer

The MS9001B and MS9001B1 are the latest multfunctonal optical spectrum analyzers with high-speed and accurate measurement capablties. The MS9001B/B1 is best for optical commununication wavelengths. The MS9001B/B1 covers wavelengths up to 1.75 um and can be used to measure 1.55 um band light-emitting elements developed for long-distance optical communications as well as the loss characteristics of optical parts and materials using white-light sources (MG922A). The diffraction gratings used in other spectrum analyzers have polarization characteristics. Therefore, the measured level of a polarzed light source such as an LD is not stable and the level accuracy cannot be guaranteed.
