Folded Eye Diagram Theory of Operation
The "folded eye" tool provides the capability to perform an eye mask measurement using the enhanced
bandwidth setting. The oscilloscope tool cannot create an eye mask with the bandwidth enhancement
enabled. This is because the bandwidth enhancement requires a periodic waveform. So this tool builds an
eye by triggering on a pattern marker (and so requires a repeating pattern) and stepping through the
pattern to fold each bit around one Unit Interval. This tool works with the Bandwidth enhancement
enabled in the Global Tool Settings dialog box under the Edit pull-down menu.
