National Instruments Releases PCI 6-1/2-Digit Digital Multimeter
Engineers can dramatically reduce the time it takes to make accurate measurements on the PCI bus with National Instruments full-featured 6-1/2-digit digital multimeter (DMM)---the new NI PCI-4070 FlexDMM. The unique multifunction capability of the FlexDMM and its tight integration with LabVIEW 7 Express measurement software gives engineers the flexibility, resolution, input range and isolation required for challenging applications such as fuel cell testing and high-resolution data converters.
The FlexDMM can operate as both a full-featured 6-1/2-digit DMM and a 1.8 MS/s high-voltage isolated digitizer. It delivers 6 parts per million basic 24-hour DC voltage accuracy and sub microvolt sensitivity. The FlexDMM offers a DC reading rate from 100 S/s at 6-1/2 digits to 10 kS/s at 4-1/2 digits. As a digitizer, the FlexDMM can acquire both AC and DC-coupled voltage and current waveforms up to 300 V and 1 A input at a maximum sampling rate of 1.8 MS/s. With the FlexDMM, engineers can make a variety of non-standard measurements, including instantaneous power, that were traditionally solved using a specialized instrument such as a power meter.
Engineers can quickly increase the channel count of their PCI or PXI-based DMM system by easily integrating with NI switch modules, such as the NI PXI-2530 128x1 multiplexer and the NI SCXI-1129 256 crosspoint high-density matrix. When engineers use the FlexDMM with NI switch modules and NI Switch Executive switch management software, they can measure thousands of channels with a single multimeter. The FlexDMM ships with NI-DMM driver software, which is optimized for use with NI LabVIEW and LabWindows/CVI, and Microsoft Visual Studio .NET.
