Compress Digital VI

Owning Palette: Digital Waveform VIs and Functions

Requires: Base Development System

Compresses the digital signals in the digital input and returns the result in the digital output. Wire data to the uncompressed digital waveform input to determine the polymorphic instance to use or manually select the instance.

DWDT Compress Digital

	force compression? specifies whether the compression is performed even if the data already appears to be compressed.
	uncompressed digital waveform is the waveform you want to compress.
	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.
	compressed digital waveform returns the compressed waveform.
	error out contains error information. This output provides standard error out functionality.

Compress Digital Details

Use the Compress Digital VI to compress digital data when you want to display two or more serial digital signals with the same bit sets on the same row to better visualize the data. For example, if you acquire 10 digital waveform samples and nine waveforms are identical but the tenth waveform differs, compressing the digital data helps you easily find which waveform is different. Compressing digital data also conserves memory resources. Use the Uncompress Digital VI to uncompress digital data you compress.
