The Keysight M9407B is a PXIe low-noise amplifier and filter module engineered to enhance receiver measurements in RF test systems. This 2-slot, 2U module integrates a low-noise amplifier, switching matrix, and filter bank to provide a low-noise signal path for sensitive receiver-based measurements. It operates in standard bypass mode and draws power directly from the host PXI chassis.
