Use the N2891A 70-MHz high-voltage differential probe to make safe and accurate floating measurements with an oscilloscope. The N2891A differential probe allows conventional earth-grounded Keysight oscilloscopes to be used for floating signal measurements of up to ±7000 V of differential and common mode voltage.
The probe is compatible with any oscilloscope with 1 MΩ BNC input. The probe power is supplied by included 4x AA batteries or USB host port of the scope or PC via a supplied USB power cable.
