The Keysight / Agilent N28xxA / N28xxB Series Passive Probes provide up to 500 MHz bandwidth and feature a high input resistance of 10 MΩ for low probe loading. These probes provide a 10:1 attenuation ratio except for the N2889A which provides a switch in the probe handle for switching the attenuation ratio between 1:1 and 10:1. The probes are compatible with Keysight / Agilent InfiniiVision and Infiniium Series oscilloscopes with 1 MΩ BNC input. The N284xA Series passive probes are the frequency tuned versions of the N2862B/63B/89A/90A, offering more linear frequency response with Keysight / Agilent oscilloscopes.
