  • Page 23: Accuracy

    PCI-DAS4020/12 board is ±7.0 LSB. Each PCI-DAS4020/12 board is tested at the factory to make sure that its actual worst case error is less than ±5.0 LSB. Allowing for a 10% guard-band, the absolute worst-case error of a board is ±5.5 LSB. Typical accuracy can be calculated from the various component typical errors in a similar fashion.
