Hello --
I've attached an example that illustates hardware synchronization between a PXI-4472 and PXI MIO device. The code allows the board to maintain tight synchronization but run at different sampling rates if desired. (I don't know if you are using a DSA product like the 4472 for the accelerometer measurements -- it is a very good acquisition board for sound and vibration).
If you are using only one board, you will not be able to acquire single points on the thermocouple while a continuous acquisition is in progress for the accelerometers.
Two possible workarounds come to mind. You could stop the accelerometer aquisition, grab a temperature point, and restart it. This is a bit awkward, so you could also just define 2 channels in your sca
n list and acquire both the thermocouple and accelerometer continuously. You would get lots of excess data for the thermocouple, but it should be straightforward to use array manipulation to disregard all but a small fraction of it.
