PCI-4065 DMMs from NI

National Instruments (NI) has announced that it is now expanding its line of digital multi-meters (DMMs) with low-cost 6½-digit instruments for conventional PCI bus systems as well as PCIe platforms. These DMMs complement NI's existing 407x series of 6½-digit and 7½-digit FlexDMMs. DMM pricing starts at under Rs.58,916 ($1,300).

NI's latest PCIe-4065 DMM, for example, is billed by the company as the first-ever DMM for the PCIe bus. Its counterpart, the PCI-based PCI-4065 offers measurements of DC or AC voltage and current, and both 2-wire and 4-wire resistance measurement capability.

Speed-resolution trade-off
These DMMs also make diode tests, offer ±300Vdc/rms isolation, and can make current measurements up to 3A. These DMMs offer 6½-digit resolution at up to ten readings/s, and up to 3,000-readings/s at lower resolution.

The PCIe-4065 DMMs also rely heavily on NI's software. For example, NI-DMM Soft Front Panel software, and DMM/Switch Express VI software, let users either mimic benchtop DMM displays or build high channel-count data-logging systems; users can do that in short order using NI SignalExpress software.

For automated test systems, NI's 4065 Series DMMs are also compatible with NI TestStand, LabVIEW, Labwindows/CVI and Measurement Studio.

High channel-count logging
Users can also integrate these DMMs with stand-alone switching, using the 4-slot or 12-slot USB switching mainframes, available from NI. They can configure these switch systems, controllable from any available USB port on the PC or laptop, with more than 50 available SCXI switch topologies.

For existing SCXI switch systems, the 4065 DMMs can also provide control via an auxiliary connector on their front panels. Switching offers a simple method of channel expansion for data-logging systems.
