National Instruments PXIe-4080 PXI Digital Multimeter

The National Instruments PXIe-4080 (Part Number: 783129-01) is a 6.5-Digit Onboard 1.8 MS/s Digital Multimeter. This high-performance PXI Digital Multimeter provides the measurement capabilities found in a high-resolution DMM and a digitizer, which are two common test instruments. As a DMM, the NI PXIe‑4080 delivers accurate AC/DC voltage that ranges from ±100 mV to ±300 V, as well as AC/DC current that ranges from ±20 mA to ±1 A. In addition, the DMM offers 2‑ or 4‑wire resistance, frequency/period measurements, and diode tests. In the high-voltage, isolated digitizer mode, the PXIe‑4080 can acquire waveforms at maximum sample rates of 1.8 MS per second. 

The NI PXIe‑4080 has an input impedance of 1 MΩ ± 2% in parallel with 150 pF, maximum DC voltage component of 250 V, and common mode rejection ratio (CMRR) >70 dB (DC to 60 Hz). This Digital Multimeter has a frequency range from 15 Hz to 500 KHz and period measurement range from 2 µs to 66.67 ms. The device has a current mode fuse rating T 1 A 400 V, time-lag user-replaceable Minimum interrupt rating: 500 A Littelfuse 0477001.MXP. The power consumption of the device is less than 9 W from the PXI Express backplane. It consumes a maximum of 0.55 A from both a +12 V load and a + 3.3 V load.

The device operates using the NI-DMM driver software which is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, ANSI C or Visual Basic. The device hardware can be configured using the Measurement & Automation Explorer (MAX) tool.

The PXIe-4080 has an ambient temperature range of 0.0 C to 55 0 C and a relative humidity range of 10% to 90% (noncondensing) in an operating environment. The storage ambient temperature range is -40 °C to 70 °C and the maximum altitude is 2,000 m (at 25 °C ambient temperature). The device weighs 12 oz., and measures 8.5 x 0.8 x 5.1 in. in dimensions. The PXIe-4080 has a recommended warm-up time of 60 minutes.
