Compresses the digital signals.

force compression?

A Boolean value that determines whether the compression is performed even if the data already appears to be compressed.

True	The compression is performed.
False	The compression is not performed if the data already appears to be compressed.

Default: False

uncompressed digital waveform

Digital waveform you want to compress.

This input appears when you wire a waveform to uncompressed digital data. If you wire digital data to uncompressed digital waveform, this input changes to uncompressed digital data.

uncompressed digital data

Digital data you want to compress.

This input appears when you wire digital data to uncompressed digital waveform. If you wire a waveform to uncompressed digital data, this input changes to uncompressed digital waveform.

compressed digital waveform

Compressed digital waveform.

This output appears when you wire a waveform to uncompressed digital data. If you wire digital data to uncompressed digital waveform, this output changes to compressed digital data.

compressed digital data

Compressed digital data.

This output appears when you wire digital data to uncompressed digital waveform. If you wire a waveform to uncompressed digital data, this output changes to compressed digital waveform.

Compressing Serial Data Signals

Use the Compress Digital node to condense 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 all are identical except one, compressing the digital data helps you easily find which waveform is different. Compressing digital data also conserves memory resources.
