Yokogawa Ando AQ6370D Optical Spectrum Analyzer (600–1700 nm)

The Yokogawa Ando AQ6370D is a premier telecom-class Optical Spectrum Analyzer (OSA) engineered for high-precision optical component characterization and transmission system analysis. Covering a versatile wavelength range of 600 to 1700 nm, it provides world-class spectral resolution and close-in dynamic range, making it an indispensable instrument for optical R&D labs and industrial manufacturing facilities.

Built on advanced diffraction grating technology, the AQ6370D features an optimized monochromator that delivers a high optical resolution down to 0.02 nm and an ultra-high close-in dynamic range of 78 dB (typical). With support for both single-mode and VCSEL-sourced multi-mode optical fibers, the AQ6370D easily evaluates optical transceivers, laser diodes, optical amplifiers, and DWDM network signals with outstanding measurement speed.
