Agilent/Keysight N2792A

The Keysight N2792A is a 200 MHz differential probe designed for high-voltage signal measurements in power electronics and automotive applications. It delivers a 10:1 attenuation ratio with 1 MΩ input resistance and 3.5 pF input capacitance to minimize circuit loading. The probe connects to any 50 Ω BNC oscilloscope input and operates from either an internal 9V battery or USB power.
