PXI Programmable Step Attenuator Module M9168C DC to 26.5 GHz M9168E DC to 50 GHz Data Sheet
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.
Applications
– RF signal path attenuation simulation – Engineering verification – RF receiver sensitivity test – Adjacent channel interference
Features
– 0.03 dB insertion loss repeatability through-out the operating life of up to 5 million cycles per section – Broad attenuation range of 0 to 101 dB with 1 dB step – High attenuation accuracy and flatness of ± 0.4 dB at 26.5 GHz (M9168C) and ± 0.97 at 50 GHz (M9168E) – Soft front panel is available for ease of use Customer values – Peace of mind in technology from Keysight who has a proven track record of providing versatile, quality, RF and microwave step attenuators – Reduce downtime for recalibration, improve testing efficiency and therefore maximizing throughput – Maximize measurement accuracy and system flexibility – Guaranteed precise measurements and stability across a wide temperature range Introduction
