Need scope to do ethernet and usb eye diagram testing. Eye diagrams provide instant visual data that engineers can use to check the signal integrity of a design and uncover problems early in the design process. Histogram of threshold crossing 1 one bit unit interval ui histogram crossing 2 data sample time shaded area is proportional to probability of a bit error or ber time figure 2.
To maximize acquisition quality and vertical accuracy be sure to adjust the vertical scale of the channels in which the signal is being input.
Which product is right for your exact requirements. Eye diagram tutorial analyzing signals using the eye diagram by gary breed editorial director t he eye diagram is a useful tool for the qualitative analy sis of signal used in digi tal transmission. 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. The eye diagram allows for quick visual inspection of the signal quality of high speed serial signals.
