Notes: 1. Specifications assume differential input scan, unfiltered.
2. Accuracy specification is exclusive of noise.
3. Unipolar ranges are not available for WaveBook/516, /516A, or /516E when a WBK11A, WBK12A,
or WBK13A option is installed. Unipolar ranges are available with WBK10A and any option.
