Transitional Acquisition Mode
In Transitional acquisition mode, the timing analyzer samples data at regular
intervals, but only stores data when there is a level transition on currently
assigned bits of a pod pair. Each time a level transition occurs on any of the
bits, all bits of the pod pair are stored. A time tag is stored with each stored
data sample so the measurement can be reconstructed and displayed later.
Conventional and Transitional Comparison
One issue when using transitional timing is how many transitions can be
stored. The number depends on the mode and frequency of transition
occurrence. The following overview explains the number of transitions
stored for each transitional timing mode and why.
