The Keysight N2873A is a 500 MHz passive probe delivering 10:1 attenuation for general-purpose oscilloscope measurements. Its 10 MΩ input resistance and 9.5 pF input capacitance minimize circuit loading while maintaining high signal integrity. The compact 2.5 mm probe head and spring-loaded, replaceable tip design enable precise probing of densely populated ICs and surface-mount devices. Automatic probe ID readout provides seamless integration with compatible Keysight oscilloscopes.
