The Keysight N2873A is a 10:1 passive probe delivering DC to 500 MHz bandwidth for general-purpose oscilloscope measurements across demanding test environments. Its 2.5 mm probe tip diameter provides exceptional access to densely populated IC layouts and surface-mount devices without sacrificing contact reliability. The spring-loaded probe tip maintains consistent contact while insulating IC caps ensure precise lead centering and prevent cross-pin shorting. Probe ID readout enables automatic recognition by compatible Keysight oscilloscopes, streamlining setup and configuration.
