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.
The PXI-4072 offers a DC reading rate from 10 kS/s at 4

digits
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).
