The Keysight N2751A InfiniiMode differential probe delivers 3.5 GHz bandwidth for high-fidelity signal acquisition across multiple measurement modes. Its InfiniiMode technology enables switching between differential, single-ended, and common-mode configurations without probe reconnection, eliminating setup delays and simplifying multipoint diagnostics. High input impedance and low input capacitance minimize loading effects and preserve signal integrity on sensitive circuits.
