PXI Source Measure Unit

4-Channel, ±6 V, 500 mA PXI Source Measure Unit—The PXIe‑4144 is a high‑channel‑count, high-speed source measure unit (SMU). The PXIe‑4144 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.
