The Keysight E5404A Pro Series Soft Touch Connectorless Probe delivers high-performance signal acquisition for logic analysis without traditional connector hardware. This single-ended probing solution integrates directly into PCB layouts via a industry-standard connectorless footprint, reducing mechanical footprint by 30% compared to earlier Pro Series designs. Micro spring-pin technology maintains signal integrity across board surface variations and minor contamination, while the top-side retention module eliminates back-side access requirements—critical for densely populated or thick board assemblies.
