Notes:

1. Higher rates and/or Transient capture require addition of PCI expansion card hardware at extra cost. The added channels cannot be used for streaming and the streaming channels cannot be used for fast transient capture.

2. Competitors’ data is stored to a proprietary disk in proprietary format not visible to Windows. Transcription is required before data can be utilized outside of vendor’s own application, which becomes very time-consuming on large files.

3. “Y” indicates that a real-time algorithm records (at least) maxima and minima of blocks of high-speed streaming data for accurate waveform displays at the monitor’s resolution, and fast overviews when large files are opened for viewing. Hi-Techniques name for this technology is ClearVU.

4. Optional Analog filter cards may be added to transient capture cards, which are themselves an extra-cost option.

5. All information is taken from published PDF product brochures from the respective manufacturers’ web sites in October 2004. Stated step response error is inherent in commercial sigma-delta ADC components.
