Keysight / Agilent B1511A Source/Measure Unit (SMU)
The Keysight B1511A (Agilent) Source/Measure Unit (SMU) is an advanced measurement module designed for precision in semiconductor parameter analysis. As a core component of the Agilent / Keysight B1500A Semiconductor Device Parameter Analyzer, the B1511A integrates robust voltage and current source capabilities with high-resolution measurement functionalities, making it ideal for comprehensive electrical characterization.
This versatile SMU excels in DC current-voltage (IV) measurements, offering extraordinary resolution down to a few femtoamperes (fA) and microvolts (µV). For users demanding even greater precision, the optional Atto-Sense Switch Unit (ASU) allows for enhanced sub-fA performance, ensuring that even the smallest signals can be confidently captured.
In addition to standard measurements, the B1511A offers capabilities for Quasi-Static Capacitance-Voltage (QS-CV) assessments. This critical measurement method provides insights into low-frequency capacitance-voltage characteristics necessary for evaluating the performance of semiconductor devices, especially regarding their gate surface states and high-frequency responses. With integrated leak current compensation, the B1511A ensures accurate QS-CV measurements under various conditions.
Coupled with the EasyEXPERT software, the Keysight B1511A becomes an invaluable tool for the characterization of a wide range of devices, including semiconductor materials, nanotechnology elements like carbon nanotubes (CNT) and carbon nanowires (CNW), as well as both active and passive components.
