National Instruments PXIe-4081 7½-digit digital multimeter

The NI PXIe-4081 7½-digit high-performance DMM and 1.8 MSa/s isolated digitiser offers engineers the flexibility, resolution and isolation needed to tackle challenging applications that require smarter test systems in industries ranging 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.
