The NI PXI-4071 is a 7½-digit FlexDMM - a high-performance, 3U PXI Digital Multimeter (DMM) that provides the measurement capability found in two common test instruments, a high-resolution digital multimeter and a digitizer. As a digital multimeter, the NI PXI-4071 delivers fast, accurate voltage measurements from ±10 nV to 1000 V, current measurements from ±1 pA to 3 A, and resistance measurements from 10 µO to 5 GO, as well as takes frequency/period and diode measurements. In the high-voltage, isolated digitizer mode, the PXI-4071 can acquire waveforms at sampling rates up to 1.8 MS/s. Using the analysis functions in NI LabVIEW, you can analyze these waveforms in both the time and frequency domains. The PXI-4071 offers the superior speed, accuracy, and functionality necessary on both the production floor and in R&D.

Integration with PXI Switches
Use the PXI-4071 DMM with PXI switches to form a multichannel, high-voltage data acquisition system. You can combine the NI PXI-2584 12-channel, 600 V multiplexer with the PXI-4071 digital multimeter to test fuel cells or battery stacks at up to 500 VDC common-mode isolation. The NI PXI-2527 64-channel, 300 V multiplexer offers a higher-channel-count solution for lower-voltage, high-accuracy measurements. To see more switch configurations, see “PXI Switches” on the Resources tab.

Improve Measurements with Amplifier Accessory
The NI PXI-4022 is an accessory module consisting of a high-speed, high-precision amplifier that conditions signals for acquisition by a PXI DMM. With the guarding functionality, you can make 6-wire resistance measurements for resistors connected in parallel on complex printed circuit board. For low-current measurements, the NI PXI-4022 amplifier and high-precision resistors create a feedback current amplifier. This minimizes burden voltages and converts current to voltage, so you can measure picoampere signals with femtoampere noise. To learn more about how to combine this module with a PXI Digital Multimeter, see “PXI-4022 Guard and Current Amplifier” on the Resources tab.
