The N4827A is a PCB socket adapter engineered to minimize ground inductance and preserve signal integrity in high-frequency test environments. Designed for direct PCB soldering, it serves as a dedicated test point interface that enables clean probe access without compromising measurement fidelity. Each kit includes two adapters.
– Technical Specifications
• Product Type: PCB socket adapter
• Form Factor: PCB mountable
• Package Contents: Kit of 2 adapters
• Primary Function: Ground inductance minimization and signal fidelity optimization
– Key Features
• Direct PCB mounting via solder attachment
• Optimized geometry for low-inductance ground paths
• Dedicated test point architecture for reliable signal access
• Compact form factor suitable for dense PCB layouts
– Typical Applications
• High-frequency signal measurement on production and development boards
• Passive probe attachment points where signal integrity is critical
• Test fixture integration requiring minimized parasitic inductance
• Multi-point signal acquisition in complex test setups
– Compatibility & Integration
The N4827A interfaces directly with Keysight’s 5 mm passive probe family:
• N2862B
• N2863B
• N2889A
• N2890A
This adapter is the preferred solution for applications where standard via-based test points introduce unacceptable ground inductance or signal degradation. Installation requires standard PCB soldering processes compatible with lead-free and conventional solder profiles.
