For details, see: chapter 11.3.4, "Trigger Settings for Digital Signals and Parallel

Additionally, you can define trigger holdoff conditions in the "Sequence" tab. See also:
"Holdoff mode" on page 81.
Automatic Measurements
Several automatic time measurements can be performed on digital signals. As for all
measurements, the instruments analyzes the type of the measurement source and dis-
plays only measurement types appropriate for the selected measurement source. If a
digital channel is selected as measurement source, the positive pulse measurement
(width of a positive pulse) is set as default measurement.
Statistical evaluation of time measurements and limit tests are also possible. The result
of the limit test can initiate an action, for example, stopping the acquisition or saving the
waveform.
Eye/Jitter measurements and histogram measurements on digital sources are not avail-
able.

Cursor Measurements
Cursor measurements can be performed on digital signals and unclocked parallel buses.
In this case, only vertical cursor lines are used, and the corresponding time measurement
results are displayed: t1, t1, Δt, and 1/Δt. The instrument decodes the bus value at the
cursor position and indicates it as Y-value.
