Some motion control applications require that you execute a move and
record the locations where external triggers happen. To accomplish this,
you must use the high-speed capture functionality of NI motion controllers.
The implementation for high-speed capture is divided into the buffered and
non-buffered high-speed capture methods.
Buffered high-speed capture lets you create a buffer that holds captured
positions that you can read asynchronously from the motion controller.
The motion controller automatically arms the next high-speed capture, and
writes the captured high-speed data into its onboard buffer. The enabling of
high-speed capture occurs on a firmware-timed basis, which provides
better frequency than the non-buffered high-speed capture method.
