Agilent/Keysight 34102A

The Keysight 34102A is a low-thermal input cable assembly engineered specifically for the 34420A Nano Volt/Micro Ohm Meter. This 1.2 meter shielded 4-conductor cable minimizes thermal electromotive forces (EMFs) that degrade measurement fidelity in precision low-voltage and low-resistance applications. The cable terminates with a custom mating connector on one end and copper spade lugs on the other, providing direct interface to the 34420A instrument.

Shielding and low-thermal construction preserve signal integrity where thermal gradients would otherwise introduce significant errors.
