Thanks to the presence of 2 comparators on each of A, B, D, E inputs it is possible to measure Time Interval, Accumulated Time Interval, Time Interval Single, Phase and Accumulated Phase between 2 trigger points inside the same signal.
This can be useful for measuring intervals inside multi-level a signal, e.g. TDR measurement.
Another example is measuring time interval from start on input A positive slope to input A negative slope to input B positive slope to input B negative slope. This can be achieved by selecting Time Interval A, A2, B, B2 and specifying trigger levels and slopes accordingly (see Figure 30).
However, Time Interval A to A to A to A is not possible since that would require 4 different trigger conditions on input channel A, while only 2 comparators are present.
