Multi-Chassis DSA Synchronization

You can synchronize up to 14 PXI devices in a single PXI chassis using sample clock timebase synchronization. You can synchronize up to 17 PXI devices in a single PXI chassis using reference clock synchronization. You can also synchronize DSA operations among multiple PXI chassis. Multi-chassis DSA synchronization requires that each PXI chassis include an NI PXI-665X. The NI PXI-665X devices must be programmed to share the Sync Pulse, the Start Trigger, and either the Sample Clock Timebase or Reference Clock between chassis, depending on the desired synchronization method. The software for the NI PXI-665X includes several example programs illustrating multi-chassis DSA synchronization.
