Kelvin Triaxial Cable
The triaxial cables are good for low current measurements. However, two cables are necessary for
low resistance Kelvin measurements.
Agilent Technologies designed a special Kelvin triaxial cable for the precision semiconductor
parameter analyzers. This cable is optimized for both low current and low resistance measurement.
Both force and sense lines are held rigidly in the same Teflon cable. Friction is reduced and the
cable is less sensitive to noise caused by moving the cable.
Kelvin triaxial cable assemblies are available with two connector options:
16494B B1500/4156 compatible on one end; 4142 compatible on the other end
16493K B1500/4156 compatible on both ends (standard option)
