Source / Measure Units

Testing complex systems at a high degree of reliability is a challenging task. Engineers require a precision source / measure unit (SMU), an instrument that combines a source and a measure function on the same channel. Keysight courses cover the mandatory applications to help you develop a deeper understanding of SMUs.
