The Keysight M9170A is a single-slot PXI attenuator and switch driver module that provides independent control of RF and microwave step attenuators and electromechanical switches in automated test systems. The module delivers dual independent banks—each with 12 channels—and features a graphical soft front panel (SFP) for intuitive device selection, switch path routing, and attenuation level configuration. PXI-hybrid compliant, it maximizes chassis slot utilization while maintaining biasing compatibility across a wide range of switches and attenuators.
