PXIe-4142

The PXIe-4142 is a 4-channel source measure unit (SMU) ideal for high-pin-count applications. It features 4-quadrant operation, and each channel has integrated remote (4-wire) sensing for accurate measurements. The fast sample rate of the PXIe-4142 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.
