Viewing Data using Eye Diagrams. Eye diagrams (Figure 1a) are created with sampling oscilloscopes and consist of multiple traces of data bits triggered by a bit clock. It pro-vides at-a-glance evalua- tion of system perfor-mance and can offer insight into the nature of channel imperfections. An eye diagram is a pattern shown on an oscilloscope that depicts a fuller view of what a digital signal stream looks like from a more holistic viewpoint, one could say. 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. Configure Eye Measurements. The traces are superimposed in persistence mode showing the envelope of amplitude and timing fluctuations. Transmission line phenomena must be understood and confronted, especially regarding impedance matching. • Eye diagrams are generally calculated empirically – Convolve random data with pulse response of channel – Pulse response is derived by convolving the impulse reponse with the transmitted symbol • For eye diagrams to represent the worst-case, a large set of random data must be used An eye diagram is a useful tool for understanding signal impairments in the physical layer of high-speed digital data systems, verifying transmitter output compliance, and revealing the amplitude and time distortion elements that degrade the BER for diagnostic purposes. Eye Diagram Analysis In digital communications, an eye diagram provides a visual indication of how noise might impact system performance. For more information, see Eye Diagram Analysis. Other Eye Diagram topics.

In eyeline mode the eye-diagram display shows contin-uous traces instead of synchronous dots. Viewing Data using Eye Diagrams.

If … As the frequency rises, new issues emerge. All data types are cast as double before the block displays results. Overview.

This allows pattern dependent effects to be investigated. The 71501D can perform eye-diagram analysis such as extinction-ratio testing and mask testing. What’s actually happening is that the oscilloscope is receiving, or sampling, a digital signal (a stream of step functions that represent 0s and 1s in varying patterns.) The accuracy of the eye diagram analysis increases as the number of symbols passed through the eye diagram object increases. The eye diagram object creates a series of vertical histograms from zero to T seconds, at Ts second intervals, where T is a multiple of the symbol duration of the input signal and Ts is the sampling time. The following … Plot an eye diagram and choose the Eye Measurements tab. Here you can select the Eye Diagram and define the Threshold. In a radio system, the point of measurement may be prior to the modulator in a transmitter, or following the demodulator in a receiver, depending on which portion of the system requires examination. The data eye diagram is a methodology to represent and analyze a high speed digital signal. Automated Eye Diagram Measurement Results. Eye diagram analysis is valuable in design, debugging, and maintenance. Two diagnostic tools commonly used in signal integrity analysis are eye diagrams and bathtub curves (Figure 1).
