The N2877A is a deluxe accessory kit engineered to extend the probing capability of Keysight N2870A Series passive probes. It delivers a complete set of specialized tools for signal acquisition on high-density circuit boards, fine-pitch components, and surface-mount devices. The kit combines multiple probe tips, grounding solutions, IC clips, positioning tools, and adapters—enabling access to challenging test points while maintaining measurement integrity in modern electronic designs.
Technical Specifications
Probe tips include spring-loaded gold-plated variants (0.5 mm, 5 pieces) and rigid CuBe tips (0.5 mm, 5 pieces). Grounding accessories feature HF compensated leads and standard ground leads (22 cm and 11 cm lengths) with multiple termination options: 4 mm banana plugs, 2 mm banana plugs, miniclips, and 0.8 mm sockets. Self-adhesive copper pads measure 2×2 cm (10 pieces). QFP IC clips accommodate pitch down to 0.5 mm. Adapters support 2.5 mm to 0.8 mm socket conversion and BNC integration.
– Key Features
• Dual-adapter configuration (2.5 to 0.8 mm sockets, 2 pieces) for flexible interconnection
• IC caps in five pitch grades: 0.5 mm (green), 0.65 mm (blue), 0.8 mm (gray), 1.0 mm (brown), and 1.27 mm (black)—three pieces each
• QFP IC clips in long (13 mm) and short variants, both rated to 0.5 mm pitch
• Micro SMD clip for ultra-fine surface-mount probing
• Bernstein adjustment tool for precision probe positioning
• Two-leg probe positioner for stable, hands-free measurement setup
• Color-coded rings (12 pieces: 3 sets of 4 colors) for circuit identification
• Sprung hooks (standard and short, 2.5 mm) plus pico hooks (black and red, 2 pieces each)
– Typical Applications
Designed for probing densely populated PCBs, integrated circuits with sub-millimeter pitch spacing, and surface-mount assemblies where standard probe tips cannot access test points. HF compensated ground leads support high-frequency signal integrity. Self-adhesive copper pads enable temporary ground reference points on non-conductive substrates.
– Compatibility & Integration
All accessories are engineered specifically for the N2870A Series passive probe platform. The 2.5 mm probe tip diameter standardizes across interchangeable components. BNC adapter and banana plug terminations integrate with standard laboratory instruments.
