Useful for parallel testing of multipin semiconductor devices, the PXIe-4143 SMU (source- measure unit) from National Instruments provides four channels in a single-slot 3U PXI Express module. It also features NI SourceAdapt technology, which allows engineers to custom-tune the SMU response for any DUT load.
The PXIe-4143 offers four-quadrant operation to source or sink up to ±24 V at ±150 mA. In addition, the unit achieves a sample rate of up to 600 ksamples/s to measure fast transient responses. Four current-measurement ranges are available—10 µA, 100 µA, 1 mA, 10 mA, and 150 mA—with a sensitivity of 10 pA for accurate characterization of idle currents.
