Noise Performance

Table 6-4 below summarizes the noise performance for the PCI-DAS6014/6013. 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.
