National Instruments PXI-4070 PXI Digital Multimeter
The NI PXI-4070 (Part Number: 778274-01) 6.5 Digit FlexDMM has high throughput rates, while keeping up precision and stable estimation. With National Instruments restrictive FlexDMM innovation, this DMM gives a completely separated, high-voltage digitizer capable of acquiring waveforms at sampling rates up to 1.8 MS/s at all voltage and current ratings. Utilizing the analysis capabilities available in NI LabVIEW programming, the user can dissect these waveforms in both the time and frequency spaces. The NI PXI-4070 DMM has superior speed, precision, and functionality, making it an excellent fit for use in computerized tests on both the production floor and in R&D applications.
The PXI-4070 can be used with NI-DMM, which is an IVI-consistent driver that accesses the entire functionality of the DMM through a simple-to-utilize application programming interface (API) and is compatible with languages like C/C++, .NET, Visual Basic, LabVIEW, and LabWindows/CVI. This unit also offers a 1.8 MS/s Flexible-Resolution Isolated Digitizer and the possibility to vary the resolution of the FlexDMM from 10 to 23 bits by changing the sampling rate. In addition, the Digital Multimeter includes a one of a kind multi-instrument functionality that limits general framework cost by eradicating the need to buy a different data acquisition device, signal conditioning, fixturing, etc.
The device is coupled with both DC and AC systems. Its DC system has the following features: a range/function change of 100/s, a resistance auto-range time of 50 ms, a trigger latency of 2 μs, and a maximum trigger rate of 6 kHz. Its AC system has the following features: a range or function change of 10/s, an auto-range time of 250 ms, a trigger latency of 2 μs, and a maximum trigger rate of 1 kHz.
The National Instruments PXI-4070 additionally has a built-in self-calibration feature. The self-calibration or Self-Cal feature enhances preciseness by addressing errors from temperature changes and long-term drift. Self-Cal guarantees preciseness over the complete 0 to 55 degrees Celsius operating temperature range. In addition, an external calibration every two years helps decrease downtime and maintenance expenses.
The PXI-4070 had a Last Time Buy Date from National Instruments in December 2018 and is now obsolete—but the digital multimeter will still be available in perpetuity for purchase and repairs with Apex Waves!
