Agilent/Keysight U4207A

The Keysight U4207A is a single-ended, direct connect probe designed for logic analysis applications requiring high-channel-count signal acquisition. This 34-channel probe features a 4 × 160-pin configuration with zero ohm impedance and a Standard Soft Touch Pro footprint for reliable mechanical interfacing.

Technical Specifications

• Channels: 34


• Pin Configuration: 4 × 160-pin


• Impedance: Zero Ω


• Connector Type: Direct Connect Probe with Standard Soft Touch Pro footprint

Key Features

• Single-ended direct connection architecture eliminates intermediate adapters


• Integrated with RC tip network topology optimized for U4164A logic analyzer performance


• Zero ohm characteristic impedance minimizes signal distortion in probing circuits


• Standard footprint enables consistent mechanical repeatability across test configurations

Typical Applications The U4207A addresses LPDDR4 memory interface characterization and high-speed digital bus probing when integrated with compatible BGA interposer solutions. Signal integrity measurements on memory subsystems benefit from the probe's 34-channel capacity and direct analyzer connection.

Compatibility & Integration This probe is designed exclusively for use with Keysight BGA interposers incorporating an RC tip network specified for U4164A logic analyzers. Integration with the W6602A LPDDR4 rigid BGA interposer requires two U4207A probes per interposer to establish dual connections with two U4164A analyzer modules. Direct connection to U4164A logic analyzer modules eliminates external cabling requirements. Installation and detailed system configuration guidance is provided in the W6600A-series LPDDR4 BGA Interposers Installation Guide and the U4200A-Series Probes and Cables User Guide.
