The NI PXIe-4140 is a high-channel-count, high-speed source measure unit (SMU) with four identical SMU channels per PXI Express slot. Each SMU offers 4-quadrant operation to source or sink ±10 V at ±100 mA, and each channel has integrated remote (4-wire) sensing for accurate measurements. To help reduce measurement times and capture transient device characteristics, each SMU can sample up to 600,000 S/s. Additionally, source measure rates of up to 15,000 S/s allow quick I-V characterization of devices under test.

For high-pin-count applications, you can load 17 NI PXIe-4140 modules in a single 19 in., 4U PXI chassis to provide a total of 68 SMU channels. A high-speed sequencing engine allows all of these SMUs to be synchronized with each other or with other instruments such as switches or high-speed digital test modules.
