The Keysight N2796A is a 2 GHz single-ended active probe engineered for high-speed signal acquisition with minimal DUT loading. It delivers 1 MΩ input resistance and 1 pF input capacitance, preserving signal integrity across digital design, component characterization, and research applications. The probe integrates directly with Keysight InfiniiVision and Infiniium oscilloscopes via AutoProbe interface, eliminating external power supply requirements.
