Product Overview

RENT YOKOGAWA AQ6375E Optical Spectrum Analyzer (Call for Availability)


The Yokogawa AQ6375E can quickly measure optical characteristics of devices, such as LD, LED light sources, and optical amplifiers. It also has a touch screen and a zoom feature to make it easier to use. Due to the diffractive technology used, the monochromator in some circumstances could generate high order diffracted light, which appears at wavelengths equal to the integral multiple of input wavelengths. By cutting incoming light below 1150 nm with the built-in filter, the AQ6375E drastically reduces the influence of high order diffracted light on the measurement. Thus, the measured data are always reliable and replicate the real signal under test.

The AQ6375E covers not only the wavelength span used in communications, but also the 2µm region which is used for environmental sensing, medical, biology and industrial applications. It can measure optical power from +20dBm down to -70dBm thanks to its high-dynamic and very low noise components and circuits used for photo detection. This enables precise measurements of both high power and low power sources. The AQ6375E uses a double-pass monochromator structure to achieve high wavelength resolution (0.05 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.
