Tektronix P6105 10X Passive Scope Probe

The Tektronix P6105 is a 10X passive oscilloscope probe engineered for general-purpose signal measurement and circuit characterization in applications requiring DC to 100 MHz bandwidth. This miniature probe delivers 1 MΩ input resistance and 15–47 pF input capacitance, minimizing loading effects on the circuit under test. The 10X attenuation factor—maintained within 3% at DC—extends dynamic range while preserving measurement accuracy across compatible oscilloscope platforms.
