The Keysight/Agilent/HP 5959-0288 is a set of 20 through-hole IC clips engineered for direct probing of integrated circuits during development, validation, and troubleshooting workflows. Each clip features hook-style grasping geometry designed to secure around IC pins and component leads without requiring permanent board modifications. This passive probing accessory integrates with Keysight/Agilent/HP logic analyzers and general-purpose probing systems to enable low-noise, high-speed signal acquisition across multiple test nodes simultaneously.
## Technical Specifications
• Quantity: 20 clips per set
• Input system impedance: 100 kΩ in parallel with approximately 8 pF
• Capacitive loading: 8 pF at the probe tip
• Rise time: 2 ns with ± 5% perturbations
• Compatible pin dimensions: 0.63 mm (0.025 in) square pins, or round pins 0.66 mm to 0.84 mm (0.026 in to 0.033 in) diameter
• Signal ground: Supported at probe tip for high-speed timing signals
## Key Features
• Through-hole IC clip design—grasps pins directly without soldering or PCB modification
• Low 8 pF capacitive loading minimizes signal distortion and preserves signal integrity
• 2 ns rise time supports high-speed digital and timing measurements
• Hook-style contact geometry for secure, repeatable connections
• Compatible with standard 0.025 in and 0.026–0.033 in pin dimensions
• Passive probing eliminates active circuitry complexity and power requirements
## Typical Applications
• IC functional and timing verification during prototype development
• Multi-node signal acquisition on breadboards and test fixtures
• Logic analysis of digital circuits under dynamic conditions
• Non-invasive probing where soldering is impractical or undesirable
## Compatibility & Integration
These clips function as part of Keysight/Agilent/HP passive probing systems, which include grabbers, probe leads, pods, and probe cables. They integrate directly with logic analyzer platforms and serve as an alternative to surface-mount grabbers (such as HP 5090-4356 for fine-pitch surface-mount applications). The clips provide a flexible solution for temporary test connections to target systems requiring 0.025 in or 0.026–0.033 in pin spacing.
