Filename: hws_low_level_read.vi
Requirements: View

This VI uses the low-level HWS read functions to read data from a HWS file in blocks specified by a front panel control. This may be useful when reading a very large HWS file or when only a certain section of the waveform is needed for analysis.

To run the VI:
1. Select a file location of the HWS file that you would like to read back.
2. Set the size of the block reads by setting the "# of samples to read at a time" control.
3. Set the initial location to begin reading from the file by setting the "Initial file position" control.
