RSG2488 can operate as an IEEE 1588 transparent clock, ordinary clock, master clock and supports both 1-step and 2-step operations. The available PTP module also allows the RSG2488 to get timing information from GPS and serve as a grandmaster clock for downstream time recipients.

The RSG2488 supports IEEE 1588 (PTP), SNTP, IRIG-B and GPS. It can convert time between all of these formats.
