I need to be able to output a chirp (some short signal) to an amplifier and right after record on 8 analog channels. Recording the channels seems to be no problem, but I can't seem to find a way to create my own signal and output it via IOtech's DaqBoard3000. Is anyone familiar with outputing a created signal with this board? If so, is there an easy VI or what can I do?
I've done a lot of reading and tried to do a lot of searching, but just don't seem to be getting anywhere with this board.

I wasn't sure if this was NI boards only. Is there a forum for labVIEW support for non-ni boards? IOtech doesn't seem to have such a resource.
My problem is figuring out how to output your own, manually built signal. If I can get that far I'm sure I can figure out how make a working data structure. The only data output VIs I can find are those to create program defined waves (sines, saw, etc) in either a counted or continous format. I've really only been working with the included examples. Attached is one of the examples. I'm not sure if the subVIs are included.

You could try posting to the LabVIEW board.
What you need to find is a lower level function in the IOTech driver. Something that does a direct write and not just predefined waveforms. If the VI that generates the predefined functions is not locked or password protected, look to see what is being called.
