The AQ6370E is a high-performance spectrum analyser, manufactured by Yokogawa Test and Measurement. It can measure a wavelength range from 600 nm to 1700 nm and is suitable for communications and general-purpose applications. It features high wavelength accuracy, high wavelength resolution, high dynamic range and wide level range. It also features a fast measurement mode, a high near-end dynamic range mode, APP functionality and a large touch screen LCD. It is a powerful, easy-to-operate and stable spectrum analyser.

The Anritsu Anritsu MS9740B is a benchtop spectrum analyser with wide dynamic range, high resolution and fast scanning speed for fabricating and evaluating optical active devices such as VCSEL modules, LD-modules, DF-LDs, FP-LDs, LEDs and more. It has a wavelength measurement range of 600 nm to 1750 nm and supports multimode fibre input. It also has a variety of measurement functions and menu screens to measure optical centre wavelength, level, OSNR, spectral width and other evaluation items at once and display the results on a single screen.

The Anritsu MS9740B is a high-performance spectrum analyzer that can be used to measure the polarisation mode dispersion (PMD) of optical fibres.PMD is a transmission characteristic of optical fibres that affects the performance and stability of high-speed optical communication systems. To ensure the quality and reliability of your optical fibres, you need to test them for PMD on a regular basis.

The Yokogawa AQ6370D is a spectrum analyzer for communications and general purpose applications that measures the wavelength range from 600nm to 1700nm with high accuracy, high resolution, high dynamic range and fast measurement.The AQ6370D is available in two models, the standard version and the high performance version, the high performance version provides higher wavelength accuracy and dynamic range. The AQ6370D also features a unique free-space input design that allows simultaneous testing of single-mode and multimode fibers.The AQ6370D is one of Yokogawa's most popular spectrum analyzers and is widely used in optical communications, optical amplifiers, lasers, LEDs and other applications.

Spectrum analyzer is an instrument used to measure the wavelength, power, spectrum and other parameters of a light source, which is widely used in the fields of optical communication, information processing/storage, biomedicine and so on. In these fields, the performance requirements for spectrum analyzers are getting higher and higher, such as wavelength accuracy, dynamic range, power range and so on. To meet these requirements, Bing has launched a spectrum analyzer with world-class optical performance, the Yokogawa AQ6370D.

The AQ6370D is available in standard or high performance versions. It has wavelength resolution settings from 0.02 nm to 2 nm, wavelength accuracy of 0.02 nm (C+L bands), and a maximum horizontal sensitivity of -90 dBm. The high-performance model has a near-field dynamic range of 70 dB (1 nm peak, 0.05 nm resolution) to 50 dB (0.1 nm peak, 0.02 nm resolution). The stray light rejection ratio is greater than or equal to 70 dB and the scan time is less than 0.2 sec. For 100 nm wavelength range.

Optical communication is a communication technology based on the transmission of optical signals, while fiber optic communication is a communication method that uses optical fiber as a transmission medium. Spectral analysis plays a crucial role in optical and fiber optic communications, which can accurately measure and analyze optical signals to ensure the stability and performance of the communication system.
