The DSA8200 and DSA8300 are two digital serial analyser sampling oscilloscopes, both of which can be used for testing and analysing a wide range of high-speed serial devices, such as communications, computers and consumer electronics.

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.

An oscilloscope is an electronic instrument used to display and observe signal waveforms and related parameters, which can observe and directly measure the shape, amplitude and period of signal waveforms, whose shape is shown in the figure. All electrical parameters or physical quantities that can be converted into electrical signals can be converted into equivalent signal waveforms for observation, such as current, electrical power, impedance, temperature, displacement, pressure, magnetic field, etc.
