The '''Tektronix P6202''' is a 500 MHz active 10× FET probe with 50 Ω output impedance, introduced in 1976. The 6202 has its own mains power supply, the 6202A (1980) has a [[Connectors#Lemo S-series|LEMO connector]] fitting the [[7000-series scopes]]' probe power outlets. | The '''Tektronix P6202''' is a 500 MHz active 10× FET probe with 50 Ω output impedance, introduced in 1976. | ||

Rise time of a [[P6202]] 500 MHz FET probe measured on a [[7S12]] plugin in a [[7844]] mainframe (with 25 ps [[S-52]] pulse generator head and 25 ps [[S-4]] sampling head). Measured rise time ~440 ps observed on this specimen is equivalent to 795 MHz bandwidth. | Rise time of a [[P6202]] 500 MHz FET probe measured on a [[7S12]] plugin in a [[7844]] mainframe (with 25 ps [[S-52]] pulse generator head and 25 ps [[S-4]] sampling head).
