The Keysight L4445A provides digital outputs to control switches, attenuators and other devices. The outputs can also be used to drive LEDs that to indicate the switch position. Digital inputs can be used to read back the actual position of the switch or attenuator. The L4445A provides power and control signals for many of the most popular microwave switches and attenuators.

The Y1150A-Y1155A distribution boards enable ease of wiring to the external switches. One L4445A with accessories can drive up to 64 switch coils, thats 32 SPDT switches. The L4445A supports extended channels with additional 34945EXTs.
