NI introduces source-measure-unit and switch modules
-- Test & Measurement World, 2/21/2008 9:24:00 AM
National Instruments has introduced its first PXI source-measure unit (SMU) as well as two high-density PXI switches, products that the company says can be used in semiconductor parametric tests and electronic device and component validation. Engineers can use these modules to characterize voltage and current parameters on high-pin-count devices.
The NI PXI-4130 is a programmable high-power 3U PXI module that features a single isolated SMU channel with a four-quadrant ±20-V output that incorporates remote four-wire sense. This channel can source up to 40 W in quadrants I and III and sink up to 10 W in quadrants II and IV. An additional power-supply channel handles voltage and current source and readback. The five available current ranges offer measurement resolution down to 1 nA.
The NI PXI-2535 and PXI-2536 switch modules offer 544 crosspoints, which NI claims is the largest matrix density available for a single 3U PXI slot. The PXI-2535 is configured as a 4x136 one-wire matrix; the NI PXI-2536 is configured as an 8x68 one-wire matrix. The modules provide switching speeds as high as 50,000 crosspoints/s.
Base prices: PXI-4130—$2499; PXI-2535 and PXI-2536—$2999. National Instruments, www.ni.com.
