We are trying to track AO software buffers using the 6036E (no Fifo), we need to

[Rawly]

stop the buffer at the end or beginning so there is bumpless transfer when updating the scans in the buffer. We output a sine wave so the end of the cycle will be at 0 volts, has anyone come across this before , we are using Labview 6.1 with latest NI-daqWe have been looking at the cards that provide a Fifo buffer on board, this generates an interupt every half buffer, we havent go a Fifo on the 6036E so we have to track the buffer that is created, we have tried various things like checking AO write to see when a buffer has been completed but by the time it has updated and we have stoped the output, around 30ms has passed therfore scans have been ouputed. Any ideas people

To find which cards have onboard FIFO, please open LabVIEW Help and then the last item is Hardware Capabilities. Here you will find the hardware capabilities for a range of cards and of the fatures mentioned is Input FIFO as well as Output FIFO. This will give you an idea about the onboard FIFO for different cards.

And also, I would would suggest you to take a look at the bunch of examples on analog output that are available at the following location:

Please do let me know if you haev any questions.
