HP / Keysight / Agilent 84940A Overview
The Agilent 34980A multifunction switch/measurement unit with the Agilent 34945A switch/attenuator driver is the recommended replacement product. The Agilent 34945A switch/attenuator driver module for the 34980A multifunction switch/measure unit allows you to control switches and attenuators external to the 34980A Mainframe.
You can also consider using 11713A attenuator/switch driver. The Agilent 11713A attenuator/switch driver provides GPIB or ''local'' front panel drive control for programmable attenuators and electromechanical switches. 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). For more information.
