PXI Source Measure Unit

4-Channel, ±6 V, 500 mA Precision PXI Source Measure Unit—The PXIe‑4145 is a high‑channel‑count, high-speed, high-precision source measure unit (SMU). The PXIe‑4145 offers 4-quadrant operation, and each channel has integrated remote (4‑wire) sensing for accurate measurements. The high channel count and high current capability of this module make it ideal for testing a wide range of semiconductor devices from radio frequency integrated circuits (RFICs) to optoelectronics devices such as LEDs. You can combine multiple channels to produce higher current levels. You can also perform high-speed I‑V measurements on a variety of components including diodes and organic LEDs using the onboard hardware sequencing engine. You can custom-tune the PXIe‑4145 response to any load to achieve optimum responses with maximum stability and minimum transients.
