Software
Calibrating the NI PXIe-4339 requires the installation of NI-DAQmx on the calibration system.
Driver support for calibrating the NI PXIe-4339 was first available in NI-DAQmx 14.5.1. For
the list of devices supported by a specific release, refer to the NI-DAQmx Readme, available on
the version-specific download page or installation media.
You can download NI-DAQmx from
LabWindows™/CVI™, C/C++, C#, and Visual Basic .NET. When you install NI-DAQmx, you
only need to install support for the application software that you intend to use.

For voltage verification and adjustment, connect the calibrator to the TB-4339/B/C as shown in Figure 2.

  • Page 6: Test Conditions

    The following setup and environmental conditions are required to ensure the NI PXIe-4339 meets published specifications. • Keep connections to the NI PXIe-4339 as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements. •...

  • Page 7: Voltage Mode Accuracy Verification

    Voltage Mode Accuracy Verification Complete the following steps to verify the voltage mode accuracy of the NI PXIe-4339. Set the calibrator to standby mode (STBY). Connect the calibrator to the TB-4339/B/C as shown in Figure 2. • If the calibrator has a guard connection, leave it disconnected.

  • Page 8: Ratio Mode Accuracy Verification

    Ratio mode verification uses paired channels in voltage mode to measure the excitation voltage of the ratio mode channel that is being verified. The paired channels are connected via internal circuitry on the NI PXIe-4339. The channel pairs are CH0 and CH1, CH2 and CH3, CH4 and CH5, and CH6 and CH7.
