Synchronization across a Network

    Last Modified: August 1, 2019

    The onboard 100 MHz oscillator automatically synchronizes to other network-synchronized devices that are part of your local IEEE 802.1AS subnet.

    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. They can be configured to use the IEEE 1588-2008 protocol profile instead.[1]

    • 1 IEEE 1588 protocol is supported in NI-DAQmx 18.1 and later.
