Each value describes the jitter for a symbol transition (even when the current and the
previous symbols are the same). The jitter value is implicitly given in the unit [s] and
denotes the delta between the time of the ideally expected transition (given by the data
rate) and the actual one. Positive values describe a transition that is occurring after the
ideally expected transition. The values are limited to the range -1.0e-3 to +1.0e-3. Any
values outside this range are limited to this range.
After the values in the file have been exhausted, the jitter values are taken starting
from the beginning of the file.

DUT
The "Define DUT" dialog allows you to switch between different transmission (and
reflection) paths of the DUT and to configure its DC properties. In addition, it allows
you to switch between the real DUT (with measured frequency response) and an ideal
one (with flat frequency response), which can be useful when configuring the other eye
diagram blocks (see
Chapter 5.17.2.6, "Advanced Settings dialog"
