Tektronix P77STFLXA Flex-Circuit Probe Tip with Active Buffer Amplifier

Overview

The P77STFLXA is an active flex-circuit solder-in probe tip with an integrated buffer amplifier, operating from 15 to 20 GHz. It uses TekFlex connector technology, which combines high-speed signal paths with integrated power and communication support in a single connector interface. The flex-circuit material enables soldered, multi-point connections directly to the device under test, while the close proximity of the active buffer amplifier to the measurement point ensures high-fidelity measurements with minimal signal loss.
