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 specifications describe the performance met by a majority of models.
• Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Nominal unless otherwise noted.

Conditions

Specifications are valid under the following conditions unless otherwise noted.

• Ambient temperature of 23 °C ± 5 ºC 1

• Chassis with slot cooling capacity ≥38 W 2
  – For chassis with slot cooling capacity = 38 W, fan speed set to HIGH

• Calibration interval of 1 year

• 30 minutes warm-up time

• Self-calibration performed within the last 24 hours

• niDCPower Aperture Time property or NIDCPOWER_ATTR_APERTURE_TIME attribute set to 2 power-line cycles (PLC)

15 When source-measuring, both the NI-DCPower Source Delay and Aperture Time properties affect the sampling rate. When taking a measure record, only the Aperture Time property affects the sampling rate.
16 Load dependent settling time is not included. Normal DC noise rejection is used.
17 As the source delay is adjusted or if advanced sequencing is used, maximum source update rates may vary.
18 Pulse widths and logic levels are compliant with PXI Express Hardware Specification Revision 1.0 ECN 1.
