SUMMARY
This discussion focuses on modeling the ground and signal lead impedances of a scope probe, specifically a typical 10x oscilloscope probe. The key components include the impedance of both leads and the capacitance of the probe, measured in picofarads (pF). To accurately model the inductance, users should consider the loop inductance formed when the probe tip and ground lead are connected in close proximity. A schematic for a 10x scope probe is recommended as a starting point for this modeling process.
