Specifications
35
Accuracy
100 kS/s sampling 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 averaging of 100 single-channel readings.
Each PCI-DAS6030 and PCI-DAS6032 is tested at the factory to assure the board's overall error does not
exceed accuracy limits described in Table 2.
