Displaying an Eye Pattern on My Oscilloscope

Question:  Can you please tell me how to use a scope to measure the eye-opening of digital signal?  And, is it true that only certain scopes have this capability?

Answer:  Any real-time scope can display an eye with varying degrees of clarity. The faster the oscilloscope is able to re-trigger, the clearer the eye.

For complete (and fully illustrated)  instructions on displaying an eye pattern on your scope, please visit this this page on our website.

For even more advanced jitter and eye analysis the DPOJET software can be used. For quick eye measurements the easiest method is to use the “One-touch wizard”.
