The Keysight 16493L is a high-current triaxial cable engineered to connect Ground Units (GNDU) to Switching Matrix Subsystems (SWM) or connector plates in parametric test systems. Rated for 4.2 A DC and 200 V, it delivers four times the current capacity of standard triaxial cables while maintaining the ability to measure low currents down to sub-pA levels. This dual-range performance makes it essential for both power device characterization and precision semiconductor testing.
