• NI-VMM is an IꢀI-compliant driver that accesses the complete
functionality of the VMM through an easy-to-use application
programming interface (API).
2-digit digital multimeter
that achieve remarkable throughput rates while maintaining precision and
stable measurement accuracy. With National Instruments proprietary
FlexVMM technology, these VMMs also provide a fully isolated, high-
voltage digitizer, capable of acquiring waveforms at sampling rates up to
1.8 MS/s at all voltage and current values. Using the analysis functions
in National Instruments LabꢀIEW, you can analyze these waveforms in
both the time and frequency domains. The NI 4070 VMMs have superior
speed, accuracy, and functionality, making them an excellent fit for use in
automated tests on both the production floor and in an R&V environment.
• Dompatible languages include D/D++, .NET, ꢀisual Basic, LabꢀIEW,
and LabWindows/DꢀI.

Recommended Switching and Accessories
NI PXI-2527
• Users can vary the resolution of the FlexVMM from 10 to 23 bits
by simply changing the sampling rate, as reflected in Figure 1.
• The unique multi-instrument functionality minimizes overall system
cost by eliminating the need to purchase a separate data acquisition
device, signal conditioning, fixturing, and so on.
