AIAOShardTimebaseAndTrig_DSA This example synchronizes the clocks and trigger on two Dynamic Signal Acquistion (DSA) devices and performs continuous analog input and output. NOTE: This example is intended to show low level synchronization of various devices. DSA and S Series devices now support including channels from multiple devices in a single task. DAQmx automatically synchronizes the devices in such a task. See the DAQmx Help>>NI- DAQmx Device Considerations>>Multidevice Tasks section for further details.note: If you are using PXI DSA devices along with sample clock timebase synchronization, the master device must reside in PXI slot 2.NOTE: This code will not run "as-is" on a multifunction (MIO) DAQ device.
