Rick: You want to be sure and set allocation mode = "use FIFO memory" in your call to AO Config.vi. This will cause your waveform to be stored on the card (as long as your on-board FIFO is larger than your waveform). You can get very fast update rates from this feature.
As you know, you want to set # of buffers to 0 in AO Start.vi You may also need to set the "Allow regeneration" Boolean in AO Write.vi. If you set up AO Start for continuous output, it should generate a continuous signal until you call AO Clear.vi or quit LabVIEW. Jason Dunham SF Industrial Software, Inc.

But still, stop (complete) the VI and the output stops. Is there some thing else I'm missing? Also, I would like to know if there is a maximum frequency I can create with reasonable resolution. Thanks all.
