Abstract
A logic analyzer for measuring logic signals which are delivered by a number of targets and which are not correlated in time. To incorporate the actual time features and relationships between the data signals of various targets the logic analyzer has at least one acquisition module which can be connected to an associated target or data source. The acquisition modules have various circuit arrangements which choose between the system's internal constant-frequency, or the external target generated, clock signal for a sampling signal, and then samples and synchronizes the time uncorrelated data signals. The data signals are then compared with predetermined patterns and coincidence is indicated.
