The Yokogawa AQ6373B Optical Spectrum Analyzer (OSA) can accelerate the development and manufacturing of short wavelength lasers, passive devices and LEDs as well as equipment that uses these devices for biomedical, material processing, consumer products and telecommunication applications. Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements. With an advanced monochromator, faster electrical circuits, and noise reduction techniques, the AQ6373B achieves fast measurement speed even when measuring a steep spectrum from DFB-LD or DWDM signals, or when measuring a low power signal from a broadband light source.
