6½-Digit, ±300 V, Onboard 1.8 MS/s Isolated Digitizer, L and C Measurement Support, PXI Digital Multimeter—The PXI‑4072 is a high-performance 6½‑digit, 300 V DMM that provides the measurement capabilities found in two common test instruments: a high-resolution DMM and a digitizer. As a DMM, the PXI‑4072 delivers fast, accurate AC/DC voltage, AC/DC current, 2‑ or 4‑wire resistance, frequency, period, and basic L and C measurements, as well as diode tests. In the high-voltage, isolated digitizer mode, the PXI‑4072 can acquire waveforms at sample rates up to 1.8 MS/s.
