Power Measurements

The PXIe-4051 has two synchronized ADCs that measure voltage and current. You can use NI-DCPower to measure power flowing to the PXIe-4051.

You can use the following VIs and functions to measure both current and voltage for both channels of the PXIe-4051.

  • niDCPower Measure Multiple VI or niDCPower_MeasureMultiple function
  • niDCPower Fetch Multiple VI or niDCPower_FetchMultiple function

Power can be computed as the product of the voltage and the current. While sinking, the PXIe-4051 uses a positive convention for power measurement.
