3.12.4 Sync Operation with External Equipment
(Frame-Rate Sync Operation)
In addition to its original framing rates, the APX RS has a feature of setting up a frame
rate locked to the frequency of the sync signal from an external source. With this
feature, the system has considerably expanded its range of application. For example, it
can work in sync with a manufacturing machine running at 1350 rpm, to record the
machine’s behavior at 1350 FPS.
