This module 34945A is used to switch or change external switches and attenuators with the Keysight 34980A basic device. This module delivers the switching signals with the corresponding power for the most common attenuators and RF switches.
Corresponding distribution boards enable simple wiring to the external switches and attenuators. One of the 34945A and 34945EXT can drive up to 64 changeover switch coils. If a 34945EXT is added, a further 64 switches can be operated.
