NI PXI-4022 Amplifier Module
6-Wire Guard and Current PXI Amplifier Module
The PXI‑4022 consists of a high-speed, high-precision amplifier that conditions signals for acquisition. With the guarding functionality, you can make 6‑wire resistance measurements for resistors connected in parallel on complex printed circuit board layouts or cable test applications. For low-current measurements, the PXI‑4022 amplifier and high-precision resistors create a feedback current amplifier. This implementation minimizes burden voltages and converts current to voltage, so you can measure picoampere signals with femtoampere noise.
