The 13.1072 MHz, 12.8 MHz, 12.288 MHz, and 10.24 MHz Timebases are derived from the oscillator, and are synchronized to it. Therefore, they are also synchronized to other network-synchronized timebases on your IEEE 802.1AS subnet. This enables measurement signals to be synchronized to other devices across a distributed network.
The FieldDAQ devices use the IEEE 802.1AS protocol over the network to synchronize. They can be configured to use the IEEE 1588-2008 protocol profile instead.
