Designed as a powerful benchtop tool for general-purpose optical spectrum measurements over the wavelength range from 350 to 1750 nm, the instrument is said to be up to 40 times faster than its predecessor, the AQ6315A. The ability to sample 100001 points of data (100 times as much as the AQ6315A) enables measurement over a broad wavelength range with high resolution, while data-transfer rates during remote control via Ethernet are up to 100 times faster than for the AQ6315A.
Wavelength resolution setting ranges from 0.05 to 10nm, and wavelength accuracy is ±0.05 nm (at 633 and 1523 nm) or ±0.2 nm (from 350 to 1700 nm), while the instrument boasts a level accuracy of ±1.0 dB, level sensitivity of -80 dBm (from 900 to 1600 nm), a measurable power range from -80 to +20 dBm, a close‐in dynamic range of 60 dB (peak ± 1.0 nm, resolution 0.05 nm), and a sweep time less than 0.5 seconds.
Internal data storage of 512 Mbyte is included, and external data storage is supported via a USB interface. Ethernet RJ-45 and GP‐IB interfaces are also incorporated. A built‐in calibration source is provided for a full-automatic optical alignment and wavelength calibration, which takes just a few minutes.
The new purging feature is designed to minimise the influence of water-vapour 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 back panel.
