Length
Sets the step response length in unit intervals. A higher step response value leads to
longer measurement times. Hence it is best to set this value to the number of unit inter-
vals that is roughly needed until the ringing has subsided.
You can set the step response manually or run an estimate.
The "Estimate" sets the maximum feasible value. If it is lower than the set "Length",
then the "Length" value is overwritten.

Step position
Sets the steps position. It defines what percentage of the unit lengths are displayed
before the step response.
For example, if the "Length" is set to 20UI and the "Step position" is set to 75%, the
step response diagram displays 15 UI before the step response and 5 UI after that.

Periodic
If enabled, allows the selection of the "Periodic jitter" / "Periodic noise" components:
PJ, DDJ+PJ, PN and DDN+PN.
