The Tektronix P6247 is a 1 GHz differential active probe engineered for high-bandwidth signal measurements across disk drive design, digital IC development, and high-speed communication systems including Gigabit Ethernet, IEEE 1394 Firewire, and Fibre Channel. Its compact 6 cm³ probe head enables direct probing of surface-mount devices while delivering exceptional Common Mode Rejection Ratio performance. The probe excels in design verification, timing analysis, ground bounce troubleshooting, and pulse shape and crosstalk compliance testing of high-speed signals.
