The Agilent/Keysight 54001A is a miniature active probe engineered for high-frequency signal acquisition and circuit analysis. Operating across DC to 1 GHz, this probe delivers the low-capacitance, high-impedance characteristics required for minimal loading effects during precision measurements on densely populated circuit boards and in confined test environments.
The active probe topology reduces circuit loading through 10 kΩ input impedance and input capacitance of 0.8 pF to 2 pF, preserving signal integrity on sensitive nodes. The 10:1 attenuation ratio and ≤350 ps rise time enable accurate time-domain characterization across the full bandwidth. Maximum input ratings of ±15 V (DC + peak AC) with an absolute maximum of ±50 V (DC + peak AC) define the safe operating envelope for general-purpose measurements and margin testing.
