Agilent/Keysight N2826A

The Keysight N2826A is a replacement wire set for the N2820A and N2821A high-sensitivity current probes. Each set contains multiple replacement sensor wires (typically 5 per set) that restore probe functionality after wear or damage. These bare wires measure 22 AWG and approximately 15.5 cm to 16 cm in length, designed to interface directly with current probe sensor inputs.

The N2820A and N2821A probes enable low-level current measurements down to 500 nA with high sensitivity and wide dynamic range. The N2820A provides dual-channel simultaneous acquisition with low and high gain views, while the N2821A offers single-channel operation. Both probes integrate with Keysight Infiniium and InfiniiVision oscilloscopes via the AutoProbe interface, making the N2826A wires essential consumables for sustained measurement capability in precision current analysis workflows.
