Accuracy
1.25 MS/s rate, single channel operation and a 15-minute warm-up. Accuracies listed are for measurements
made following an internal calibration. They are valid for operational temperatures within ±1° C of internal
calibration temperature and ±10 °C of factory calibration temperature. Calibrator test source high side tied to
channel 0 high and low side tied to channel 0 low. Low-level ground is tied to channel 0 low at the user
connector.

Note 1: Averaged measurements assume dithering and averaging of 100 single-channel readings.
Each PCI-DAS6071 is tested at the factory to assure the board’s overall error does not exceed absolute accuracy
limits described in Table 2.
