The Agilent/HP 11713A Attenuator/Switch Driver is a programmable instrument that automates RF signal path control through independent management of step attenuators and electromechanical switches. Operating via GPIB (IEEE-488) or manual front panel control, it drives up to ten switch or attenuator sections with nanosecond-class response times, making it essential for high-speed RF system verification and automated test environments. The unit delivers a regulated +24 Vdc supply with peak current handling of 1.3 A (1 second) and 0.65 A continuous operation.
