NI PXI-4072

Overview

The National Instruments PXI-4072 FlexDMM, based on the NI 4070

architecture, combines the functionality found in three common test

instruments – a digital multimeter, an LCR meter, and a digitizer. This

functionality provides engineers with the 20 most common test functions

in a compact 3U PXI module, including voltage, current, capacitance,

inductance, temperature, and resistance. Integrating these measurements

in a PXI module reduces test system size and cost, increases throughput,

and shortens test development time, making the NI PXI 4072 an

excellent fit for use in automated tests on both the production floor and

in an R&D environment.

to 5 S/s at 7 digits. As a digitizer, the FlexDMM can acquire both AC-

and DC-coupled voltage and current waveforms up to ±300 V and ±1 A

input at a maximum sampling rate of 1.8 MS/s. As an LCR meter, the

FlexDMM delivers 0.25 percent basic accuracy for both inductance and

capacitance at measurement rates up to 40 S/s. Using the intuitive

NI-DMM instrument driver, you can quickly change from function to

function in a single application programming interface (API).
