My code currently runs my waveform and collects data points for 2 seconds before sending data to the "DAQmx write" function. When I highlight the execution, it looks like only the latter second of data is written into the buffer, which then plays for 2 seconds.

Your code does EXACTLY what you have programmed to do: use the waveform generated of the last iteration of your FOR loop!

Hint: there's a AppendWaveform function that you can use to append one waveform to the other…
