Yokogawa launches optical spectrum analyzers


The small variation in insertion loss at the input connector increases measurement repeatability, while the lack of physical contact with the connecting fibers ensures they avoid damage. In the SWIR and MWIR region, there are wavelengths where light shows strong absorptions due to the presence of water vapor and carbon dioxide, which can both disturb the spectral measurement. By continuously supplying pure purge gas such as nitrogen to the monochromator through dedicated connectors on the back panel, the AQ637xE can reduce the influence of light absorptions on the measurement. To improve measurement efficiency and productivity, the AQ637xE features an application (APP) mode, transforming a versatile OSA into a machine dedicated to a device under test (DUT). Enhanced user friendliness is achieved with the unit’s high-resolution, responsive 10.4-inch multi-touch capacitive LCD touchscreen, which makes operating the device even simpler and more intuitive.
