The HP/Agilent 54001A is a 1 GHz miniature active probe engineered for high-frequency measurements in dense circuit environments. Its 1.5 m cable and compact 45 mm probe body (2.5 mm diameter) enable access to crowded test points without sacrificing signal fidelity. The active design delivers low input capacitance of 2 pF and 10 kΩ input impedance, minimizing circuit loading during measurements. A 10:1 division ratio (±3%) scales signals for direct acquisition on compatible oscilloscope platforms.
