The Keysight 16494A is a low-leakage triaxial cable engineered for precision measurement of currents down to the sub-fA level. Its triaxial architecture—featuring force, guard, and shield conductors—minimizes current leakage and enables repeatable results in high-sensitivity measurement scenarios. The cable serves as a critical accessory for impedance analysis, component characterization, and applications demanding sub-femtoampere resolution.
