By the time you spend for the nice diadram you might have done the vi

Your DAQ like to have a waveform (array of values and dt ak 1/samplerate)

If you set the samplerate you know the array length , create a array of zeros, and set the values of both amplitudes ...

Since I don't want to wire others homework here are some pictures

And there are some drawbacks is room for improvement in my solution, just think of rounding errors ... and what might happen if the arrays get bigger ....
