The eye diagram that uses persistence display (bottom trace) shows the history of multiple data states; in this example the eye contains 97,000 serial data bits. The eye opening is a qualitative ...

Persistence displays also help analyze data communications signals, where they are used to display eye diagrams and state transition diagrams (Figure 3). Figure 3 The eye diagrams of the I and Q ...

QUICK EYE-DIAGRAM SCAN A DDR memory interface can be made up of many DQ (data) channels. For instance, a DDR DIMM (dual-inline memory module) consists of 64 DQ channels that equal 64 bits or 8 bytes.

The corresponding eye diagram for the data pattern (CP0) also exhibits high jitter and noise. The analysis tools provided with the R&S RTP make it possible to investigate the root causes of these ...
