The Keysight/Agilent/HP 01650-63203 Termination Adapter bridges 40-pin logic analyzer probe cables to 20-pin connectors on target systems. It consolidates signal paths through RC network termination and 100 kOhm resistance, reducing required board pins while maintaining signal integrity in digital measurement applications. The adapter interfaces with a broad range of Keysight and Agilent logic analyzer mainframes and modules, making it essential infrastructure for multi-channel digital acquisition and protocol analysis.
## Technical Specifications
• **Connector Interface:** 40-pin male to 20-pin female
• **Target Connector Compatibility:** 20-pin connectors or 2×10 headers with 0.1-inch spacing
• **Termination Resistance:** 100 kOhm
• **Input Impedance:** Approximately 12 pF in parallel with 100 kOhm
• **RC Network Termination:** Integrated RC networks for signal conditioning
• **Common Ground Configuration:** Shared ground architecture; signal fidelity may degrade with transition times faster than 4–5 ns
## Key Features
• Pin-count reduction from 40 to 20, minimizing target board real estate
• RC network integration for impedance matching and signal integrity
• Standardized 0.1-inch header spacing ensures broad compatibility with commercial connectors
• Operates across 0 to +55°C (32 to 131°F)
## Typical Applications
• Multi-channel digital signal acquisition and analysis
• Protocol decoding and timing measurements on embedded systems
• Signal integrity verification in complex digital environments
• Reduced pin-count target system integration with logic analyzer probes
