The Keysight E5405B is a 17-channel differential connectorless probe engineered for direct signal access on PCBs without requiring a physical connector on the target board. Designed for engineers and laboratories performing advanced signal analysis and characterization, this probe delivers high-speed data capture with minimal electrical loading. The E5405B uses Keysight’s Soft Touch Pro Series connectorless probing technology—an industry-standard footprint approach that reduces PCB real estate requirements in space-constrained applications.
Technical Specifications
• Channels: 17 total (configurable as 16 single-ended or differential data channels plus 1 single-ended or differential clock channel)
• Equivalent Load Capacitance: Less than 0.7 pF
• Maximum Data Rate: Greater than 2.5 Gb/s
• Minimum Signal Amplitude: 200 mV Vmax-Vmin
• Contact Technology: Micro spring-pin technology for reliable pad engagement on uneven or contaminated surfaces
• Retention Mechanism: Top-side retention module—no backside PCB access required
– Key Features
• Connectorless probing eliminates discrete connector components on the target board
• Micro spring-pin contact ensures stable electrical connection across varied surface conditions
• Topside retention simplifies probe deployment and improves workflow efficiency
• Suitable for all board surfaces, including lead-free assemblies
• Low capacitive loading preserves signal integrity for high-speed measurements
– Typical Applications
Signal characterization on high-density PCBs, embedded system debugging, complex electronic subsystem analysis, and space-limited design environments where traditional connectorized probes introduce unacceptable footprint overhead.
– Compatibility & Integration
The E5405B connects to logic analyzers equipped with 90-pin cable connectors. Deployment requires upfront design integration of the Pro Series Soft Touch connectorless footprint into the target PCB.
