Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical—describes the performance met by a majority of models.
  • Nominal—describes an attribute that is based on design, conformance testing, or supplemental testing.
  • Measured—describes the measured performance of a representative model.

    • Values are Warranted Specifications unless otherwise noted.

    1 The ambient temperature of a PXI system is defined as the temperature at the chassis fan inlet (air intake).

    2 For increased capability, NI recommends installing the PXIe-4147 in a chassis with slot cooling capacity ≥58 W.

    3 Refer to the Remote Sense and Load Regulation sections for additional accuracy derating and conditions.

    4 Temperature coefficient applies beyond 23 °C±5 °C ambient within ±5 °C of Tcal.

    5 Tcal is the internal device temperature recorded by the PXIe-4147 at the completion of the last self-calibration.

    6 Multiple-channel specifications apply whenever two or more channels are connected and sourcing/sinking current. Multiple-channel specifications account for interactions between the channels when operated at high current, including board heating.

    7 Single-channel specifications assume only one channel is connected and sourcing/sinking current which results in improved accuracy due to the reduction of effects between the channels, including board heating. When transitioning from a multiple-channel configuration to a single-channel configuration, a ten-minute cool down period is required to meet Single Channel accuracy specifications.

    8 Relative humidity between 10% and 70%, noncondensing. When operating above 70% relative humidity, add 30 pA to current accuracy specifications.

    23 Not all chassis can achieve this ambient temperature range. Refer to PXI chassis specifications to determine the ambient temperature ranges your chassis can achieve.

    24 When transitioning a device from a storage or operation environment with relative humidity above 70%, device should be allowed to stabilize in the lower humidity environment for several hours before use.
