It features 4-quadrant operation and each channel has integrated remote (4-wire) sensing for accurate measurements. The fast sample rate of the PXIe-4143 can reduce measurement times, capture transient device characteristics, and allow quick I V characterization of devices under test (DUTs). With a high-speed sequencing engine, you can synchronize all these SMUs with each other or with other instruments such as switches or high-speed digital test modules. Additionally, you can tune the PXIe-4143 response to any load to achieve optimum responses with maximum stability and minimum transients using SourceAdapt technology.<\/p>\n<h3 data-section-id=\"dprvcy\" data-start=\"0\" data-end=\"47\"><span role=\"text\"><strong data-start=\"4\" data-end=\"47\">Applications and Use Cases of PXIe-4143<\/strong><\/span><\/h3>\n<p data-start=\"49\" data-end=\"357\">The PXIe-4143 Precision Source Measure Unit (SMU) is a PXI Express <strong data-start=\"116\" data-end=\"145\">source measure unit (SMU)<\/strong> designed for <strong data-start=\"159\" data-end=\"213\">precision voltage\/current sourcing and measurement<\/strong>.
