The PXIe-4081 is the industrys most accurate 7½-digit DMM and provides the measurement capabilities found in two common test instruments| a high-resolution 1,000 V DMM and a digitizer. As a DMM, the PXIe-4081 delivers fast, accurate AC/DC voltage, AC/DC current, 2- or 4-wire resistance, and frequency/period measurements, as well as diode tests. In the high-voltage, isolated digitizer mode, the PXIe-4081 can acquire waveforms at sample rates up to 1.8 MS/s.
