Overview
The National Instruments 4070 FlexDMM is a 6
that achieve remarkable throughput rates while maintaining precision and
stable measurement accuracy. With National Instruments proprietary
FlexDMM technology, these DMMs 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 LabVIEW, you can analyze these waveforms in
both the time and frequency domains. The NI 4070 DMMs 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&D environment.
High-Speed Digital Multimeter
1.8 MS/s Flexible-Resolution Isolated Digitizer
• Users can vary the resolution of the FlexDMM from 10 to 23 bits
• The unique multi-instrument functionality minimizes overall system
Built-In Self-Calibration and 2-Year Calibration Cycle
• Self-calibration (Self-Cal) improves accuracy by removing errors due to
• Self-Cal ensures accuracy over entire 0 to 55 °C operating range.
• 2-year external calibration cycle reduces downtime and maintenance costs.
