Moreover, a hysteresis range may be specified to ignore any spurious transition that does not
exceed the boundaries of the hysteresis interval. In Figure 3, Delta c2d- (1, 2) measures the time
interval separating the rising edge of the clock (trigger) from the first negative transition of the
data signal. Similarly, Delta c2d+ (1, 2) measures the time interval between the trigger and the
next transition of the data signal.
Level and Slope
For several time based measurements, you can choose positive, negative, or both slopes to
begin parameter measurements. For two-input parameters, such as Dtime@level, you can
specify the slope for each input, as well as the level and type (percent or absolute).
