The PXI-4070 FlexDMM achieves remarkable throughput rates while maintaining precision and stable measurement accuracy. This combination of speed and accuracy was previously available only with higher resolution digital multimeters (DMMs) that cost thousands of more dollars. Thanks to the NI proprietary FlexDMM technology, this PXI DMM also provides a fully isolated, high-voltage digitizer capable of acquiring waveforms at sample rates up to 1.8 MS/s at ±300 V input. Using the analysis functions in LabVIEW software, you can analyze these waveforms in both the time and frequency domains. Because of its superior speed, accuracy, and functionality, the PXI-4070 is ideal for use in automated tests on both the production floor and in R&D environments.

Integration With PXI Switches
You also can use the PXI-4070 with PXI switches to form a multichannel, high-voltage DAQ system. The PXI-2527 64-channel, 300 V multiplexer offers a low thermal EMF solution for both high- and low-voltage measurements. The PXI-2530 128-channel reed relay multiplexer offers more density for higher channel count systems and better performance for low-current switching. For additional switch configurations, visit the PXI Switches link in the Resources section.

Improve Resistance and Current Measurements With an Amplifier Accessory
The PXI-4022 accessory module consists 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 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. For additional information on how to combine this module with PXI digital multimeters, refer to the PXI-4022 Guard and Current Amplifier link in the Resources section.
