The Keysight N2889A low-cost passive probe provides up to 350 MHz bandwidth and features high-input resistance of 10 MΩ (@10:1 mode) to address a wide range of measurement needs with low probe loading. The N2889A comes with a convenient switch in the probe handle that lets you switch between a 1:1 and 10:1 attenuation ratio.
The probe can be adjusted for low-frequency compensation and high-frequency compensation. For the best measurements you should compensate your probe to match its characteristics to the oscilloscope.

Notes:
¹ Input impedance when terminated into oscilloscopes with 1-MΩ input terminations. For higher-bandwidth Infiniium oscilloscopes with 50-Ω input terminations only, the E2697A high impedance adapter can be purchased (includes 10073D 500-MHz passive probe) to provide a 1-MΩ input termination.
² For proper probe compensation (flatness), the oscilloscope’s input capacitance must be within the specified compensation range of the probe.
³ Capacitance at the probe tip of 1:1 probes is the specified probe capacitance plus the capacitance of the oscilloscope when terminated into 1-MΩ.
