Test Equipment

The following table lists the test equipment required to calibrate the PXIe-4339.

Instrument Recommended Model Requirements
Calibrator Fluke 5700 If this instrument is unavailable, use a calibrator that can provide DC voltage values in the range of 0 to ±10 V with an accuracy of 50 ppm of output or better and a DC offset error of 4 µV or better.
PXI Express Chassis PXIe-1062Q
Connection Accessory TB-4339/B/C*
*  The terminal block variants TB-4339, TB-4339B, and TB-4339C differ only in resistance; the measurements are the same regardless of the variant used.

Test Conditions

The following setup and environmental conditions are required to ensure the PXIe-4339 meets published specifications.

  • Keep connections to the device as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
  • Verify that all connections to the device, including front panel connections, are secure.
  • Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets.
  • Maintain an ambient temperature of 23 °C ± 5°C. The device temperature will be greater than the ambient temperature.
  • Keep relative humidity below 80%.
  • Allow a warm up time of at least 15 minutes to ensure that the measurement circuitry is at a stable operating temperature.
  • Ensure that the PXI/PXI Express chassis fan speed is set to HIGH, that the fan filters are clean, and that the empty slots contain filler panels. For more information, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/manuals.

Device Setup

  1. Install PXIe-4339 in the PXI Express chassis according to the instructions in the NI PXIe-4339 and TB-4339/B/C Installation Guide and Terminal Block Specifications.
  2. Configure the device identifier and select Self-Test to ensure that the device is working properly.
  3. Launch the Calibration Executive procedure. Calibration Executive guides you through the required connections.

Test Limit Equations

The following test limits are derived from the published specifications.

Gain and Offset Error Verification and Adjustment

Voltage Mode

  • Limit = Test point * (1 ± Gain Error) ± Offset Error
  • Gain Error = 0.06%

Ratiometric Mode

  • Limit = Test Point * (1 ± Gain Error) ± Offset Error
  • Test Point = (Calibrator Output)/(Excitation Voltage)
  • Gain Error = 0.1%
  • Offset Error = (Offset Error Coefficient)/(Excitation Voltage)

Refer to the NI PXIe-4339 Device Specifications for Gain Error and Offset Error values.
