Agilent/Keysight U4206A

The Keysight U4206A is a 34-channel single-ended logic analyzer probe cable engineered for direct connection between a system under test and compatible Keysight logic analyzer modules. Equipped with Soft Touch Pro connectors, this probe delivers high-speed digital signal acquisition and analysis capabilities for complex debugging and validation workflows. The cable terminates in four 160-pin connectors on the analyzer end and a Soft Touch Pro connector on the probe end, enabling straightforward integration with U4164A and related Keysight logic analyzer platforms.
