Using the Eyeline Mode
Using the Eyeline Mode
The eyeline mode is mainly used for noise reduction in eye diagrams.
When a periodic pattern is sampled it is possible to average over several
patterns in a similar way as in normal averaging mode. An eyeline trace is
obtained when the averaged pattern is folded back into an eye diagram. In
order to produce a full eyeline trace several samples must be recorded
from all bits in the pattern. Hence, the longer the pattern the more time it
will take to acquire all samples.
To use the eyeline mode:
1. Select the pattern view mode using the button at the bottom of the
screen.
