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.

Inputs/Outputs

  • cbool.png force compression? —

    force compression? specifies whether the compression is performed even if the data already appears to be compressed.

  • cdigwdt.png uncompressed digital waveform —

    uncompressed digital waveform is the waveform you want to compress.

  • cerrcodeclst.png error in (no error) —

    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.

  • idigwdt.png compressed digital waveform —

    compressed digital waveform returns the compressed waveform.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    • 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.
