Resistance Measurements Using Precision SMUs
Application Notes
The B2900C/CL Series Precision Source/Measure Units (SMUs) are designed to perform precise resistance measurements across a wide range of values. This application note details the methods and features that enhance measurement accuracy, such as eliminating residual lead resistance effects through 4-wire connections, compensating for offset voltages and thermal electromotive forces, and preventing leakage currents with active guard functions. Additionally, the note includes practical lab exercises to demonstrate the use of these features in real-world scenarios, making it an invaluable resource for engineers and researchers working with resistors and other devices.
