The Tektronix TAP4000 is a 4 GHz single-ended active FET probe engineered for high-speed digital circuit verification, debug, and characterization. This 10X attenuation probe minimizes loading effects on test points while delivering rise times of ≤115 ps and propagation delay of 5.3 ns, enabling accurate signal acquisition across demanding measurement scenarios. The compact probe head accommodates small-geometry circuit elements, with DUT attachment accessories supporting Surface-Mount Devices as small as 0.5 mm pitch.
