Net.Time

Net.Time GM is a general purpose PTP Grandmaster conceived to supply synchronization to clients connected to Ethernet / IP networks such as 4G / LTE base stations and Synchronous Ethernet as well. Once locked to a GPS it delivers highly accurate timestamps, alternatively 10 MHz, 1PPS, T1/E1 and TOD can be used as backup. For testing porpoises, the unit can loopback Ethernet frames to remote instruments executing quality and capacity test. The unit is a rack mount chassis, with AC/DC power source.
