National Instruments has expanded its low-cost digital multimeter offering with the NI PXI-4065, a new 6½-digit multimeter for PXI. The low cost of the PXI-4065 digital multimeter along with its 6½-digit performance offers a new entry point for reliable, high-channel-count data-logging measurement systems.
Engineers can combine the new multimeter with more than 150 available NI PXI switch configurations in the low-cost NI PXI-1033 integrated chassis and controller to create high-channel-count, 6½-digit data-logging systems for up to 48 channels and $12,000 (USD) for up to 784 channels. For further system expansion, engineers can add 3,000 channels with each additional 18-slot PXI chassis.
With the NI-DMM driver software that comes with the PXI-4065 digital multimeter, engineers can build high-channel-count data-logging systems in seconds using National Instruments LabVIEW SignalExpress.
For automated test systems, NI 4065 digital multimeters are also compatible with NI TestStand, LabVIEW, LabWindows/CVI and Measurement Studio development environments, offering a variety of options for engineers to programmatically define and control their measurements.
The PXI-4065 digital multimeter uses the same technology as the existing NI PCI-4065 and NI PCIe-4065 digital multimeters, offering 6½-digits of resolution at up to 10 readings per second and up to 3,000 readings per second at lower resolutions.
With ±300 VDC/Vrms of isolation, current measurements up to 3 A and 2- or 4-wire resistance measurements, NI 4065 digital multimeters offer a complete solution for basic 6½-digit measurement needs.
For higher performance, engineers can configure systems with the existing family of NI 407x FlexDMM devices that deliver measurement speed, accuracy and resolution. Engineers also can integrate the new multimeters with modular power supplies and precision sources from National Instruments to build complete precision DC measurement systems.
About NI Modular Instruments
NI modular instruments are the building blocks for economical and versatile automated test systems.
With modular instruments, engineers specify the essential functionality they require – choosing from a wide variety of measurement, signal generation, RF, power and switch modules – then configure those instruments in software for their specific measurement tasks.
Because these instruments are modular and software-defined, they are quickly interchanged and easily repurposed to meet the challenge of evolving test needs.
NI modular instruments are available on a variety of platforms including PXI, PXI Express, PCI, PCI Express and PCMCIA and provide the advantage of high-speed test execution by harnessing the power of industry-standard PC and advanced timing and synchronization technologies.
The product family includes:
- Digitizers/oscilloscopes (up to 24 bits, up to 2 GS/s, up to eight channels)
- Signal generators (up to 16 bits, 200 MS/s)
- Digital waveform generator/analyzers (up to 400 Mb/s)
- RF signal generators and analyzers (up to 6.6 GHz)
- Digital multimeters (up to 7½ digits, LCR)
- Programmable power supplies (up to 20 W, 16 bits)
