The Keysight N2789A is a spring ground tip accessory engineered to establish reliable ground connections for Keysight 10076B and 10076C oscilloscope passive probes. This grounding solution enables proper probe operation and measurement accuracy by providing the necessary ground reference path during signal acquisition on oscilloscope channels.
Technical Specifications
The N2789A is a passive grounding accessory with no active circuitry or power requirements. Its design integrates with the mechanical interface of the 10076B and 10076C probe families.
– Key Features
• Spring-loaded ground tip design for consistent probe grounding
• Direct compatibility with Keysight 10076B oscilloscope passive probe
• Direct compatibility with Keysight 10076C oscilloscope passive probe
• Passive accessory—no external power or configuration needed
– Typical Applications
The N2789A serves as a replacement or spare grounding accessory for oscilloscope probe systems. It is used in general-purpose analog signal measurement where passive probing and ground reference stability are required. Typical deployment includes bench test environments, failure analysis, and signal characterization across general electronic circuits.
– Compatibility & Integration
This accessory is designed exclusively for use with Keysight 10076B and 10076C passive probes. The spring ground tip mechanically and electrically interfaces with these probe models to complete the ground connection path during measurement. The N2789A is not compatible with other probe families or probe types.
