A strong pulse indicates good blood flow, while a weak pulse can indicate poor blood flow or a decrease in cardiac output. Character: The character of the pulse refers to the shape of the expansion and contraction pressure waves.. The E5071C option TDR provides simulated eye diagram analysis capability, eliminating the need for a hardware pulse pattern generator. The virtual bit pattern generator is used to define a virtual bit pattern. The defined bit pattern is then convolved with the device impulse response to create an extremely accurate measurement based eye diagram.

With eye diagrams you can see signal quality with one display, you can diagnose problems, such as attenuation, noise, jitter, and dispersion that arise or characterize specific parts of the system. You can then view the measurement in the Time Domain mode to help isolate the source of the problem.. A wide and tall eye indicates good signal quality, while a closed or skewed eye highlights problems such as jitter, crosstalk, and reflections. Eye diagrams are captured using real-time or sampling oscilloscopes and simulated using EDA tools (HyperLynx or Ansys SIwave). What is an eye diagram in signal integrity analysis?
