I'm using a PXI 4461 and two PXI 4462 boards.
I'm pushing a waveform of voltage values through the analog output of the PXI 4461. At the same time that I'll be pushing these voltages into the 4461, I'll be reading voltage from multiple analog inputs on the the 4462s. From everything that I have researched, this is the VI I came up with. It seems to work, but how do I know that the timing of the output and the inputs are in sync? Is there some way of testing this?
I've attached the VI, I could use a few of you to take a look at this and offer advice.
Thanks,

Hi John,
The basic idea of synchronization is that 2 devices share a common start trigger and a common sample clock. You example appears to be a modified example that does exactly this. From your exampel you can see that the devices all share a common time base then are all started on the same start trigger.
