The Keysight N2890A is a 500 MHz passive voltage probe engineered for high-bandwidth signal acquisition across laboratory and field test environments. This 10:1 attenuation probe delivers 10 MΩ input resistance and 12 pF input capacitance, making it suitable for oscilloscopes with 1 MΩ input impedance and standard BNC connectors. The probe handles 200 V CAT II steady-state and 2500 V transient overvoltage, with a 1.5 meter lead length and replaceable sprung hook tip for versatile probing configurations.
