Agilent/Keysight N2853A

The Keysight N2853A is a 10:1 passive probe engineered for precise signal acquisition across DC to 350 MHz applications. Built for engineers and technicians requiring reliable measurements in circuit design, debugging, and validation workflows, the N2853A delivers a 1 ns calculated rise time and accommodates input voltages up to 300 VRMS CAT II. Its 10 MΩ input impedance shunted by 11 pF provides minimal loading on circuits under test, while dual-range frequency compensation - adjustable for both low and high-frequency performance - ensures signal fidelity across demanding measurement scenarios.
