The Yokogawa Test & Measurement Div. has announced the AQ6373, an optical spectrum analyzer that measures from 350 to 1200 nm. It features a color analysis function that renders it suitable for measuring LEDs and laser light sources. Wavelength accuracy is ±0.5 nm, wavelength resolution is down to 0.01 nm, and sensitivity is –80 dBm. Standard sweep time is 1 s, and 0.5 s in automatic mode. The free-space optical input makes the instrument suitable for use with single-mode, multimode and large-diameter-core fibers. A built-in light source aids optical alignment. The 10.4-in. bright display has an intuitive graphical user interface, and operation can be controlled via USB mouse, keyboard and panel keys. Internal memory of 128 MB is backed up by USB memory support. Functions include filtering, automatic measurements and pass/fail testing. Fast remote operation is available via GPIB, RS-232 and Ethernet. Applications include R&D evaluation and production testing of short-wavelength laser filters and LEDs.
