The Keysight N2879A is a fine-pitch accessory kit that extends the probing capability of the N2870A Series passive probes for precision measurements on densely populated circuit boards and surface-mount assemblies. This kit supplies specialized probe tips, grounding accessories, IC clips, and adapters to enable reliable connections to test points as small as 0.5 mm pitch, maintaining signal integrity in complex measurement environments.

– Key Features
QFP IC clips feature lever-activated grasping jaws rated for 0.5 mm pitch components. Micro SMD clips employ spring-loaded, two-pole design with flat-nosed grips for individual component access. PCB adapter kits are hand-solderable and reflow-compatible, designed for direct PCB integration to minimize ground inductance. Spring-loaded probe tips deliver balanced force for both large and small component testing.
– Compatibility & Integration
The N2879A kit integrates with Keysight N2870A Series passive probes. All PCB adapter sockets accept standard hand soldering and reflow processes.
