The 11713A attenuator/switch driver provides HP-IB or "local" front panel drive control for programmable attenuators and electromechanical switches. Concurrently drive up to two 8494/5/6/7, 84904/6/7K/L programmable attenuators and two electromechanical switches (8761, 8762, or 8765 series). The 11713A can also be used to supply +24 V common and ten pairs of current sinking contacts (total current draw <1.25A peak for 1 second, 0.65A steady state) to independent control up to 10 relays. An integral power supply with short circuit protection eliminates the need for an external power source. Each 11713A is supplied with two plug-in drive cables to simplify connection to programmable attenuators. Switching time is less than 10 milliseconds.
