By inheriting and improving upon the control technologies originally developed for the AQ6370 series, the AQ6374 achieves operating and measurement speeds more than 40 times those of the AQ6315A. Its ability to sample 100,001 data points (100 times more than the AQ6315A) enables high-resolution measurement across a wide wavelength range, while data transfer speeds during remote control via Ethernet are up to 100 times faster than the AQ6315A.
The measurement performance achieved by the monochromator technology includes a wavelength resolution of 0.05 to 10 nm, a wavelength accuracy of ± 0.05 nm (from 633 to 1523 nm) or ± 0.2 nm (from 350 to 1700 nm), a level accuracy of ± 1.0 dB, a level sensitivity of -80 dBm (from 900 to 1600 nm), a measurable power range of -80 to +20 dBm, a dynamic range close to 60 dB (peak ± 1.0 nm, resolution 0.05 nm), and a sweep time of less than 0.5 sec.
It features 512 MB of internal data storage, and external data storage is supported via a USB interface. Ethernet RJ-45 and GP-IB interfaces are also included. A built-in calibration source provides fully automatic optical alignment and wavelength calibration in just a few moments.
The new purge feature is designed to minimize the influence of water vapor absorption on spectral measurements by continuously supplying a pure purge gas, such as nitrogen (or just some dry air), to the monochromator through dedicated connectors on the rear panel.
The AQ6374 features an ergonomically designed graphical user interface for maximum ease of use, incorporating elements such as a full text menu, aggregation of measurement conditions, display of a "hard key" menu matching the panel design, and a plotting configuration menu.
Thanks to its ability to measure across a wide range of wavelengths, the AQ6374 is the ideal Optical Spectrum Analyzer for R&D teams testing light sources, optical filters, and sensors that operate in both the visible and telecommunications ranges of the spectrum.
