Keysight (Agilent) N2750A InfiniiMode Active Differential Probe, 1.5 GHz

The Keysight N2750A InfiniiMode Active Differential Probe delivers 1.5 GHz bandwidth for high-speed differential signal acquisition. A single probe tip supports four operational modes—differential, single-ended A, single-ended B, and common mode—without reconnection. The AutoProbe interface enables automatic oscilloscope configuration and probe power delivery. Switchable 2:1 and 10:1 attenuation ratios accommodate dynamic ranges from ±1 V to ±5 V, with maximum input handling of 30 V DC + peak AC and ±15 V DC offset capability. Differential input impedance is 200 kΩ ± 2%, while common mode rejection exceeds 60 dB at 1 MHz. Integrated controls manage oscilloscope functions including RUN/STOP, auto scale, and quick save. A built-in LED headlight illuminates test points for enhanced visibility.
