With appropriate configuration of digitizer modules and effective
instrument support, however, trigger or timebase synchronization,
or both can be achieved, commensurate with application require-
ments.
As shown in the following, in a simple synchronization architec-
ture, two digitizer modules receive trigger and timebase from a
function generator. With required buffering of trigger and timebase
signals and equal wiring length between the function generator
and digitizers, trigger and timebase synchronization are possible.
In this scenario, the function generator is a master device that out-
puts trigger and timebase, and the two digitizers are slave devices
sharing the same trigger and timebase.
