Q8344A，Q8344A，Q8344AAdvantest Q8344A 光譜分析儀|OSA|日本愛德萬品牌：日本愛德萬 | AdvantestOverview Q8344A is an optical spectrum analyzer with a wide wavelength range from 0.35 to 1.75 m.The usage of a Fourier spectrum system using a Michelson interferometer makes it possible to analyze coherence that cannot be obtained by the dispersing spectrum systems using monochromators. It exhibits its capabilities for evaluation of laser diodes for CDs and video disks.The built-in He-Ne laser used as the reference wavelength realizes a wavelength accuracy of ±0.1 nm (1.3 m), ensuring a long-term measurement stability even without wavelength calibration. Feature -- Coherence Measurement-- High-Speed Measurement with 1.5 Seconds/Sweep-- Well-Suited for Production UseWavelength Measurement Accuracy of ±0.1nmMaximum Wavelength Range of 0.05nmLarge-Caliber Fiber Input (Option)
