| NI Releases Low-Cost 6½-Digit Multimeters for PCI and PCI Express | |||||
NEWS RELEASE – National Instruments expands its line of digital multimeters (DMMs) with new low-cost 6½-digit DMMs for PCI Express and PCI. The NI PCIe-4065 DMM, the first-ever DMM available on the PCI Express bus, and the PCI-4065 DMM offer measurements of DC or AC voltage/current; 2- and 4-wire resistance; and diode test ideal for educational laboratories, cost-conscious test and measurement facilities and original equipment manufacturers (OEMs) who embed DC or AC measurements into an end-product or test system. The new DMMs complement the NI 407x series of 6½-digit and 7½-digit FlexDMM devices ideal for higher-performance test and measurement requirements. With the new NI 4065 DMMs, engineers can take advantage of the wide availability of PCI and PCI Express slots found in desktop computers, industrial PCs or expansion chassis to take DMM measurements in any environment – from a laboratory benchtop to a production test rack. With the NI-DMM Soft Front Panel and DMM/Switch Express VI software, engineers can either mimic benchtop DMM displays or build high-channel-count data-logging systems in seconds using NI SignalExpress. For automated test systems, NI 4065 DMMs are also compatible with NI TestStand, NI LabVIEW, LabWindows™/CVI and Measurement Studio. With ±300 VDC/Vrms of isolation, current measurements up to 3 A and 2- or 4-wire resistance measurements, NI 4065 DMMs offer a complete multimeter solution for basic 6½-digit measurement needs. NI 4065 DMMs add to the existing family of NI DMM products that deliver industry-leading measurement accuracy and resolution (see table). Engineers can integrate the new DMMs with modular power supplies, precision sources and switch modules from National Instruments to build complete precision DC measurement systems.
