I you have a 2D data array that you which to prepare for sending use this VI to create the full data cluster needed for downloading. waveform name(s) contains the names of the waveforms, channel data is the array with values controlling to which channels each waveform should be sent. The time unit controls the clock setting. Be sure to correctly partition the data with the time unit using FLCWFG Partition Raw Data.vi before calling this VI. a final check before downloading is also advisable using FLCWFG Waveform Check.vi.
