Additional Features: Simple GPIB control of up to ten switch or attenuator sections Drives two attenuators and two switches concurrently Controls up to ten 24 V relays The Agilent 11713A can concurrently drive up to two Agilent 8494/5/6/7, Agilent 84904/6/7K/L programmable attenuators and two electromechanical switches (Agilent 8761, 8762, or 8765 series). The Agilent 11713A can also be used to supply +24 V common and ten pairs of current sinking contacts (total current draw less than 0.25A peak for 1 second, 0.65A steady state) to independently control up to 10 relays. An integral power supply with short circuit protection eliminates the need for an external power source.
