The Tektronix P6247 is a 1.0 GHz active differential oscilloscope probe designed for high-bandwidth time and frequency domain measurements. It is particularly suited for disk drive design verification, high-speed digital IC design, and testing compliance of fast communication standards like Gigabit Ethernet, IEEE-1394 Firewire, and Fibre Channel. Equipped with the TEKPROBE BNC interface, it offers seamless integration, automatic scaling, and power directly from compatible Tektronix oscilloscopes.
