4-Channel, ±24 V, 150 mA Precision PXI Source Measure Unit—The PXIe‑4143 is a high‑channel‑count, high-speed, high-precision source measure unit (SMU) with four identical SMU channels. It is ideal for high‑pin‑count applications. The PXIe‑4143 offers 4-quadrant operation, and each channel has integrated remote (4‑wire) sensing for accurate measurements. With its integrated sensing and current measurement sensitivity, the PXIe‑4143 is ideal for precision measurements including accurate characterization of idle currents. 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. You can custom-tune the PXIe‑4143 response to any load to achieve optimum responses with maximum stability and minimum transients.
