The Tektronix P6247 is a 1 GHz differential probe engineered for precision measurement of high-bandwidth signals in demanding test environments. It delivers sub-350 ps rise time with minimal loading through 60 dB CMRR at 1 MHz rejects common-mode noise effectively. The probe integrates directly with Tektronix TDS oscilloscopes via TekProbe® interface, supporting auto-scaling and auto-termination. Its compact 78 mm probe head and 1.2 m cable enable access to confined test points while maintaining signal fidelity across the full 1 GHz bandwidth.
