PXI Source Measure Unit

4-Channel, ±24 V, 150 mA PXI Source Measure Unit—The PXIe‑4142 is a high‑channel‑count, high-speed source measure unit (SMU) with four identical SMU channels. It is ideal for high‑pin‑count applications. The PXIe‑4142 offers 4-quadrant operation, and each channel has integrated remote (4‑wire) sensing for accurate measurements. The fast sample rate of the PXIe‑4142 can help 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 of these SMUs with each other or with other instruments such as switches or high-speed digital test modules.
