NI PXIe-4081 Digital Multimeter

Friday, 03 June, 2016 | Supplied by: National Instruments Aust Pty Ltd

NI has launched the NI PXIe-4081 7½-digit high-performance digital multimeter (DMM) and 1.8 MSa/s isolated digitiser, offering engineers the flexibility, resolution and isolation needed to tackle challenging applications that require smarter test systems in industries from consumer electronics to aerospace and defence.

The PXI Express DMM features 15 ppm accuracy for DC voltage measurements up to two years after calibration. It is capable of voltage measurements from nanovolts to 1 kV and resistance measurements from micro-ohms to giga-ohms. A solid-state current shunt configuration offers eight DC current ranges from 1 µA to 3 A and six AC rms current ranges from 100 µA to 3 A.

The product occupies a single 3U PXI slot and provides good channel density for high-channel-count systems, delivering 17 DMM channels in a single PXI chassis occupying 4U of rack space. For high-throughput applications, the isolated digitiser mode can acquire DC-coupled waveforms in all voltage and current ranges with a 1.8 MSa/s maximum sample rate. By changing the digitiser sampling rate, engineers can vary the resolution of the digitiser from 10 to 23 bits for speed and accuracy.

Engineers can also use an interactive soft front panel for basic measurements and debugging automated applications. The driver software includes a programming interface that works with a variety of development environments, such as C, Microsoft .NET and LabVIEW. The driver also features help files, documentation and 28 ready-to-run example programs to assist in test code development.
