Noise performance
Table 4 summarizes the noise performance for the PCI-DAS6013 and PCI-DAS6014. Noise distribution is
determined by gathering 50 K samples with inputs tied to ground at the user connector. Samples are gathered at
the maximum specified single-channel-sampling rate. This specification applies to both single-ended and
differential modes of operation.
