The Keysight (Agilent) B2201A Low Leakage Switch Mainframe is a matrix switch instrument engineered for precision semiconductor testing and component characterization. It automates signal routing and switching with minimal leakage, delivering femtoampere (fA) resolution for sensitive measurements. The B2201A integrates with Keysight source measure units and parameter analyzers to reduce test cost through automated characterization across configurable triaxial and coaxial channel topologies.
