What is an eye diagram analyzer
Eye Diagram Analyzer is a technical concept in RF and microwave engineering related to test & measurement. It refers to a specific parameter, component, or methodology used in the design, analysis, or measurement of radio frequency systems. In telecommunications, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rate is used to trigger the horizontal sweep (x-axis). The name "eye diagram" comes from the distinctive shape of the graph, which resembles the shape of an eye. It reveals the quality of high-speed signals by highlighting voltage levels and timing errors.

What is the sampling waveform of an eye diagram
Typically, eye diagrams are composed of voltage/time samples of the original data, acquired at some sample rate that is orders of magnitude below the data rate. The eye diagram reflects that the digital signal is affected by the physical device and the channel. Engineer can quickly obtain the measured parameters of the signal in the product to be tested through the eye diagram, and can predict the problems that may occur in the field. For sampling oscilloscopes, this can be 105 samples per second at a 10 Gb/s (1010 bits/second) rate. PLTS constructs measurement-based eye diagrams (or patterns) by convolving the calculated time domain impulse response (generated from frequency domain measurement data) with a synthesized pattern of bit sequences.
