The Keysight (Agilent / HP) 11713A is a legacy attenuator and switch driver designed to provide local front-panel and remote GPIB control for programmable step attenuators and electromechanical switches. It features an integral 24 Vdc power supply capable of driving up to 10 independent relays, supporting concurrent operation of two programmable attenuators and two electromechanical switches without the need for an external power source.
