The Agilent/Keysight 3499A is a 5-slot switch and control mainframe engineered for high-density automated test equipment applications. This 2U rack-height mainframe supports up to five plug-in modules, enabling routing of up to 200 channels with scanning rates to 350 channels per second. The system opens/closes all 200 channels in less than 0.1 second, delivering the switching performance required for demanding production and lab environments.
