With this VI you can roll waveforms stored in the generator over a specified amount of steps (pulses). You specify the Direction [F: left (default), T: right], and the amount of steps in Step count [1…12287]. You also need to specify the channel byte, this is a number which represents the binary translation of the eight possible channels, a `true' will address that channel, e.g 2 (00000010) selects channel 2 only, 131 (10000011) selects channel 8, 2 and 1 etc. Only the selected channels will be affected.
