The 80 MHz, 20 MHz, and 100 kHz Timebases are derived from the oscillator, and are synchronized to it. Therefore, they are also synchronized to other network-synchronized timebases on your 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. These devices cannot synchronize over the network with devices that use protocols or IEEE 1588 profiles other than IEEE 802.1AS.
