Description

Basic information
Name: NI PXIe-4140 Data Acquisition Instrument/Source Measurement Unit (SMU)
Brand: National Instruments (NI)
Country of Origin: USA
Product model: PXIe-4140
Technical characteristics
High channel count: Each PXI Express slot has four identical SMU channels to support high channel count applications.
High-speed sampling: Each SMU has a sampling rate of up to 600,000 S/s, which significantly reduces measurement time and captures transient device characteristics.
Four-quadrant operation: Supports drain or source voltages in the ±10 V range at ±100 mA, providing flexible operation modes.
High precision measurement: Each channel has integrated remote sensing (4-wire) function for accurate measurement with 100 pA current measurement sensitivity.
High speed source measurement rate: up to 15,000 S/s source measurement rate to quickly record the I-V characteristics of the device under test.
Synchronization capabilities: The high-speed coding engine allows all SMUs to be synchronized with other types of SMUs or other instruments, such as switches or high-speed digital test modules.
