PCI-DAS6034 & PCI-DAS6035 User's Guide
Noise Performance
Table 4 below summarizes the noise performance for the PCI-DAS6035/6034. Noise
distribution is determined by gathering 50K samples with inputs tied to ground at the user
connector. Samples are gathered at the maximum specified single-channel-sampling rate.
Specification applies to both single-ended and differential modes of operation.
