Trigger node for measurement system

A trigger node for a measurement and control system, includes a synchronized clock 14 that maintains a time using a synchronization scheme that provides the timing precision needed for the application of stimuli and/or measurement of responses without specialized adaptation of analog signaling to the measurement and control system. The trigger node further includes mechanisms for asserting a trigger signal (22) when the time from its synchronized clock (14) matches a trigger time associated with the trigger signal (22). Multiple trigger nodes (10, 40 and 50) may be used to coordinate the timing of multiple measurement and control devices (60-66) by appropriately setting the trigger times in the trigger nodes (10, 40 and 50).
