National Instruments CAL-4330 Calibration Fixture
The National Instruments CAL-4330 (Part Numbers: 786988-01, 787003-01) Calibration Fixture is a vital component for preserving the precision and dependability of PXIe-4330 and PXIe-4331 devices. This fixture offers a controlled environment for testing and modifying different parameters, ensuring accurate calibration.
For optimal outcomes, use a Fluke 5520A/5522A calibrator with the CAL-4330. An alternate calibrator with similar specifications can be used if these particular models are not available. The necessary parameters are automated lead wire compensation, 2-wire output compensation, resistance values between 120 Ω and 1 kΩ with 0.01 Ω resolution, and an accuracy of 90 ppm or greater.
CAL-4330 comes with the cables needed to make connections easier. Two of these cables are 160-Pin DIN to 160-Pin DIN, which connect PXIe-2737 switch modules to the fixture. The other cable is a shielded cable (SH96F-96M-CAL4330), which connects the Device Under Test (DUT) to the CAL-4330.
Two DMMs, either PXI-4071 or PXIe-4081 devices, are among the test apparatus needed for calibration. These DMMs ought to be multiranging, with a 6 1/2-digit capability and an accuracy of at least 40 ppm for DC voltage and 80 ppm for resistance when measuring 4-wire resistance. Four PXIe-2737 switch modules are furthermore required for relay operations.
The CAL-4330 is designed to provide accurate readings in particular testing scenarios. It is advised to utilize twisted-pair wire to reduce noise and thermal offsets, use shielded copper wire for cable connections, and keep connections short to reduce noise interference. Stable operation conditions are achieved by keeping the relative humidity below 80% and the ambient temperature at 23°C ±5°C. In addition, it is advised to give the measurement circuitry at least 15 minutes to stabilize before running any experiments.
