The HP/Agilent 11713A Attenuator/Switch Driver provides manual and GPIB-programmable control of RF and microwave components in automated test systems. This instrument simultaneously drives up to two four-section programmable step attenuators and two electromechanical coaxial switches, while independently controlling up to ten relays via +24 Vdc common and current sinking contacts. The integral power supply eliminates external components. Front panel pushbuttons enable manual operation; one-line HP-IB statements support remote automation. Designed for precision signal routing and attenuation in laboratory and production environments.
