National Instruments PXI-4071 PXI Digital Multimeter

The NI PXI-4071 (Part Number: 778271-01) is a FlexDMM, multifunction 3U PXI module that gives the estimation ability found in a high-resolution digital multimeter (DMM) and a digitizer. As a DMM, the PXI-4071 makes quick, precise voltage estimations from ±10 nV to 1000 V, current estimations from ±1 pA to 3 An, resistance estimations from 10 µω to 5 Gω, and takes recurrence/period and diode estimations. The device has a DC current range of -3 A to 3 A. In the high-voltage, confined digitizer mode, the PXI-4071 can get DC-coupled waveforms at test rates up to 1.8 MS/s in all voltage and current modes. Utilizing the examination capacities in NI LabVIEW programming, the user can study these waveforms in time and recurrence. The PXI-4071 offers prevalent speed, exactness, and usefulness, making it a great choice for use in robotized tests.

This model outperforms traditional 7 1/2-digit DMM speed/execution boundaries by utilizing a modern architecture that exploits the fast PXI bus. At 7 1/2 digits, the PXI-4071 accomplishes DC reading rates of 7 S/s. For applications requiring higher throughput, it has a high DC reading rate of 10 kS/s at 4 1/2 digits (these rates are no less than five times quicker than the original GPIB-controlled DMMs). The device when AC coupled, has an auto range time of 250 ms (for both AC V and AC 1), a range/function change of 10/s, a trigger latency and maximum trigger rate of 2 µs and 1 kHz respectively. The device has a warm-up time of 1 hour before operation.

The PXI-4071 can import and export triggers, making it simple to coordinate them with any multiplexer/matrix switch modules. Specifically, the FlexDMM incorporates consistently with National Instruments switch offerings. For example, with NI switch modules and NI Switch Executive switch management software, the user can quantify a huge number of channels, consisting of voltages, thermocouples, RTDs, and thermistors. The user can also keep a firm control on the cost of their framework.
