state analysis we observe the behavior of the system as it is seen
from the point of view of the logic gates. It is appropriate for
capturing synchronous signals. In this type of acquisition, signals
are sam pled on the edges of the device's clock - either when rising,
falling or both. A timing acquisition, on the contrary, is driven by
the internal clock of the logic analyzer .
