The eye graph Analyzer is an electronic measuring instrument used in the field of electronics and communication technology, launched on August 1st, 2012.
Often used to test and verify electronic devices, serial digital signals in chips or high-speed digital signals, in the final analysis, it is a fast and very intuitive means of observing the quality of digital signals. In consumer electronics, high-speed signal transmission is often used within the chip and between the chip and the chip, if the corresponding signal quality is poor, it will lead to instability of the device, function execution error, and even failure. The eye map reflects that the digital signal is affected by physical devices and channels, and engineers can quickly obtain the measured parameters of the signal in the product to be tested through the eye map, and can predict the problems that may occur in the field.

An ophthalmograph is an instrument used to observe and analyze digital communication signals. It is used to diagnose the performance of digital communication system by displaying the waveform changes and related parameters of digital signal under specific conditions, such as data transmission rate, modulation type, signal-to-noise ratio, clock out of step and other parameters. Specifically, by measuring the intensity of light and changes in the time window, the ophthalmograph is able to display the eye diagram of the digital signal, that is, the display of the waveform in a cycle of the digital signal, and thus obtain the transmission quality of the digital signal. In communication engineering, as a signal analysis and measurement equipment, ophthalmograph is widely used in data communication, wireless communication, optical communication and other fields.
Electronic measuring instruments used in the field of dry electronics and communication technology.
Electronic measuring instruments are instruments that convert measurements into indicators for direct observation, including all kinds of indicating instruments, comparison instruments, recording instruments, sensing instruments and transmitters, such as eye chart instrument is used to dry electronic and communication technology field of electronic measuring instruments
An ophthalmograph, also known as a straight-eye viewer, is an instrument used to examine and evaluate human vision. Through the use of different optical prisms and test cards, the ophthalmograph can measure the degree of astigmatism, myopia and farsightedness of the human eye, as well as color vision, binocular visual field and other parameters, thus providing ophthalmologists with accurate vision diagnosis and treatment plans.
The ophthalmograph can also be used for optometry and optometry to provide patients with the best vision correction solution.
In addition to its use in ophthalmic diagnosis and treatment, ophthalmograms are also commonly used in optician services to ensure that customers have the most suitable lenses and frames to help achieve the best vision correction results.
An ophthalmograph is a device used to test and diagnose the eye. It can measure and record people's eye movements through electronic technology, so as to analyze and judge the reaction and adjustment ability of the eye to the object, as well as the health of the eye indicators.
When the ophthalmologist performs a pupil examination, mydriasis examination, or optometry examination, the ophthalmograph will provide more accurate data and image support, so that the doctor can make more appropriate treatment plans and recommendations.
In addition to being used for eye examination, ophthalmograph can also be applied to other fields, such as psychology, human-computer interaction and other research, which is of great significance for improving visual fatigue and improving user experience.
