How to continously generate a voltage signal with dynamic amplitude.

[hurzeler]

Hello all,

I am looking for ideas and pointers (help in other words). I would like to generate a voltage signal (sine for example) on a AO of my NI cRIO-9263 (DAQmx). The signal should be:

• continuous (without jumps ie. smooth)
• dynamically able to be change the amplitude, frequency and sampling rate.
• interuptable so that the AO can be turned off.

I have tried to use the DAQ Assistant but once it runs in continous mode, I have the impression that the waveform should not be changed. Is there maybe a way where I send repeatedly N samples of the waveform to the AO and gain more control over the signal that way. But if I do that how can I ensure that the signal is continous?

Further more this output has to be generated in an event application ie. in the background.

Your ideas and input is appreciated. Thanks, Bernie
