National Instruments PXI-4022

The National Instruments PXI-4022 is a high-speed, high-precision PXI Amplifier Module designed for seamless integration with digital multimeters, enhancing signal acquisition capabilities. Featuring a unique 6-wire configuration, the PXI-4022 is particularly adept at performing accurate resistance measurements in both complex PCB applications and cable testing scenarios through its advanced guarding functionality. The input terminals are constructed from low-EMF, low-leakage, gold-plated solid copper, ensuring optimal signal integrity.

This Measurement Category II rated device is engineered to handle signal voltages of 250V while providing a robust surge voltage threshold of up to 2,500V. With an impressive input impedance greater than 10^10 Ω, an input bias current of less than 5 pA, and an output voltage range of ±12V, the PXI-4022 is designed to deliver dependable performance. The module also supports a maximum output drive current of ±15 mA and is equipped with integrated overvoltage protection for its Guard terminals.

The front panel includes five signal connectors, which facilitate easy connection to various measurement setups. These include a Guard/amplifier output, Guard/amplifier positive input, Guard-Sense/amplifier negative input, and two floating common (LO) terminals. To expand versatility, two additional electrically equivalent connectors are positioned on the back of the module, representing the floating ground. The PXI-4022 can be effortlessly installed in any compatible PXI chassis and is conveniently configurable via the Measurement & Automation Explorer (MAX) software.

Specifications for the PXI-4022 confirm its compact 3U form factor dimensions of 8.5 x 5.1 x 0.8 inches and a weight of 9.7 ounces.
