The Yokogawa AQ6373 Optical Spectrum Analyzer has the ability to provide high speed, accurate analysis of the short wavelength range between 350nm and 1200nm, this OSA is well suited for a broad range of applications. The AQ6373 can accelerate the development and manufacturing of short wavelength lasers, passive devices and LEDs as well as equipment that uses these devices for the biomedical, material processing, consumer product and telecommunications markets. With built in color analysis capabilities and remote command compatibility with the AQ6315, the AQ6373 provides an upgrade of capabilities, speed and performance for current AQ6315 users. The AQ6373 achieves high speed measurements with high accuracy, resolution and sensitivity, even while providing full analysis features. Troublesome calibration steps and the development of external analysis software is no longer required. The advanced monochromator achieves high wavelength resolution and high close-in dynamic range. With the sharper spectral characteristics of the monochromator, spectral signals in close proximity can be separated clearly and measured accurately. The AQ6373 can measure a pulse peak spectrum of a pulsed light signal. Often used in the transmission loop testing of telecommunication systems, and also in the low power measurement at the early stage of laser chip development to catch the peak power of a pulsed signal.
