Trigger reception on different instrumentation devices may be synchronized
by each instrumentation device generating one or more trigger enable
signals and delaying performance of an operation in response to a trigger
signal until a transition in a trigger enable signal. An instrumentation
system may include several instrumentation devices and a communication
medium coupling the instrumentation devices. One of the instrumentation
devices may process data in response to a sample clock signal. That
instrumentation device may also generate a trigger enable signal and
delay performing an operation in response to a trigger signal transmitted
via the communication medium until a transition in the trigger enable
signal occurs. The trigger enable signal is not the sample clock signal.
The trigger enable signal may be synchronized to another trigger enable
signal generated by another one of the instrumentation devices.
