Append Digital Samples VI

Owning Palette: Digital Waveform VIs and Functions

Requires: Base Development System

Appends all samples from digital waveform B to the end of digital waveform A. If the sampling rates do not match, error out returns a warning. The start time of digital waveform B is ignored. Wire data to the digital waveform A input to determine the polymorphic instance to use or manually select the instance.

DWDT Append Digital Samples

	default value specifies the value to use to fill in the extra signals of the digital data in digital waveform out if digital waveform A and digital waveform B do not have the same number of signals. 0 0 (default)—Force Down 1 1—Force Up 2 Z—Force Z 3 L—Compare Low 4 H—Compare High 5 X—Compare Don't Care 6 T—Compare Invalid 7 V—Compare Valid
	digital waveform A is the first set of data in the digital waveform.
	digital waveform B is the set of data to append to digital waveform A.
	error in describes error conditions that occur before this node runs. With the following exception, this input provides standard error in functionality. This node runs normally even if an error occurred before this node runs.
	digital waveform out returns the waveform that results from appending digital waveform (low bits) to digital waveform (high bits). This output matches the compression of the input.
	error out contains error information. This output provides standard error out functionality.

DTbl Append Digital Samples

Appends all samples from digital data B to the end of digital data A. If the number of signals do not match, error out returns a warning. The number of samples do not have to be the same.
