Yokogawa Releases AQ6373E & AQ6374E Optical Spectrum Analyzers

Yokogawa Test & Measurement Corporation has released the AQ6373E visible wavelength and AQ6374E wide-range optical spectrum analyzers. Designed as successors to the AQ6373B and AQ6374, which feature high resolution and close-in dynamic range, the new analyzers offer the same high level of performance as well as features that improve operability to meet a variety of optical spectrum measurement needs in both R&D and production settings.

The AQ6373E optical spectrum covers the same wavelength range between 350 nm and 1200 nm as the current AQ6373B. In addition to a standard performance model, the lineup now includes a high-resolution model optimized for laser evaluation applications and a limited model designed for production testing applications.

The AQ6374E optical spectrum analyzer can be used not only for the evaluation of light-emitting devices such as lasers but also for the characterization of optical fibers. It offers the high optical performance of the previous AQ6374 model, providing the industry’s only wide measurement wavelength range (350 – 1750 nm).

The new optical spectrum analyzers both feature improved usability, including an APP mode designed to speed up customers’ R&D and production testing tasks. APP mode provides a device under test (DUT) specific user interface that navigates the user from the configuration setting to the output of test results so that even customers who are unfamiliar with optical spectrum analyzers can use them easily. They are also equipped with a large LCD touch panel, making operation even easier and more intuitive.
