National Instruments PCI-4070

The National Instruments PCI-4070 is a high-speed 6.5-digit Digital Multimeter Device, part number 778275-01, designed for use in PC-based systems. This FlexDMM excels in high-resolution measurements and can function as a digitizer, making it perfect for automated testing in research and development environments as well as on production floors. The PCI-4070 accurately measures AC/DC voltage, current, and resistance, and includes an option for diode testing. With a basic DC voltage accuracy of 25 ppm, users can rely on its precision for various applications.

Operated with NI-DMM driver software (version 3.0.2 or later), the PCI-4070 is compatible with popular application development environments such as LabVIEW, LabWindows/CVI, Microsoft Visual C++, and Microsoft Visual Basic. The multimeter features 12 built-in measurement functions and offers self-calibration capabilities. When in isolated digitizer mode, it can capture AC and DC-coupled waveforms across all voltage and current modes, allowing for the measurement of differential waveforms with high common-mode voltage.

Using LabVIEW in conjunction with this device enhances its performance to achieve a 7-digit resolution at a speed of 5 samples per second, quadrupling the resolution of standard 6.5-digit multimeters. The PCI-4070 supports multiple resolution settings in DC mode, including 7, 6.5, 5.5, 4.5, and 3 digits. Operating within a temperature range of 0 °C to 40 °C, the device’s maximum sampling rate varies based on the resolution, ranging from 5 S per second to 1.8 MS/s, with a maximum trigger rate of 6 kHz in DC mode and 1 kHz in AC mode. The instrument is compact yet robust, weighing 20 oz. and measuring 4.95 x 13.86 inches. A three-year warranty is included, and user manuals are available for download.
