Greetings,
Unfortunately, it appears that the exact example you are looking for does not exist on National Instrument's website. However, the following example synchronizes multiple PXI-4472s with NI-DAQmx:
PXI 4472 Synchronize and Stream to DiskYou may want to consider modifying this example to synchronize the PXI-4472 and PXI-6071Es in the same manner as the Traditional NI-DAQ example you referenced (divide-down the PXI-4472's Master Clock Timebase to obtain the sample clock for the PXI-6071Es, etc.)
Good luck with your application.
