Using this VI you can set the trigger data if you select the timing in the timing/waveform control or the c-bit data for the selected waveform. If the option Add? is set to true the pulses in index selection will be set to true in addition to those already present in the trigger/c-bit data. If this option is set to false only the pulses in the index selection will be set, effectively erasing all previous trigger or c-bit information. The VI returns the set trigger/c-bit data array.
