Appendix

Appendix D: 1588 Synchronized Scan Start

The 1588 protocol allows multiple MPS4000 units to start scanning at a preset time while keeping their data sample time

synchronized. The scan start preset time, SSD and SST, could be a future time or a time past. The following tables show the

time line for both cases. Please note that the frame timestamp is always relative to the start of scan time.

The following table describes a start scan with two MPS4000 units with internal trigger when the setting of SSD and SST are

in the future.

SCAN START WITH FUTURE START TIME FOR 2 MPS4264 MODULES, INTERNAL TRIGGER
