Appends the signals from digital waveform (low bits) to the LSB side of digital waveform (high bits). If the sampling rates do not match, error out returns a warning. The start time of digital waveform (low bits) is ignored. Wire data to the digital waveform (high bits) input to determine the polymorphic instance to use or manually select the instance.

Use the Append Digital Signals VI to append the signals from two separate digital waveforms into a single digital waveform. You can append signals with the same number of samples or of different numbers of samples. For example, if you have two digital signals that both consist of two rows of 8 bits, the resulting digital data consists of two rows of 16 bits. If you combine two signals, one that consists of two rows of 8 bits and the other that consists of one row of 8 bits, the resulting digital data consists of two rows of 16 bits. The Append Digital Signals VI pads the remaining columns in the second sample with the value you select in the default value input.
