Keysight Technologies, Inc. has been a leading designer and manufacturer of RF and microwave step

attenuators in the global marketplace for more than 60 years. RF and microwave attenuators are used

extensively in microwave test systems for signal conditioning between transmitting and receiving of a

device under test (DUT). Keysight designs and manufacturers a comprehensive range of RF and microwave

attenuators to meet your signal attenuation requirements. There is a broad range of fixed, manual, and

programmable step attenuators with operating frequencies from DC up to 4/18/26.5/40/50 GHz.

Product Description

Other than connectorized standalone attenuators, Keysight also offers step attenuator modules that

operate across a broad frequency range of DC to 26.5/50 GHz. The M9168C/E is a programmable step

attenuator module based on the PXI hybrid platform, with 0.03 dB insertion loss repeatability for each

section throughout the 5 million cycles operating life. Its excellent attenuation accuracy across a wide

operating temperature range ensures precise measurements. The M9168C/E is a signal conditioning

module that enhances the measurement accuracy and flexibility of PXI based RF and microwave test

systems.
