Agilent/Keysight N2819A

The Keysight N2819A is an 800 MHz differential probe engineered for high-speed signal acquisition on compatible Keysight oscilloscopes. It connects directly via AutoProbe interface, drawing power from the oscilloscope's probe port and eliminating external supply requirements. The probe delivers 10:1 attenuation, 200 kΩ input impedance, and sub-nanosecond rise time performance suitable for precision measurements across power delivery networks, automotive bus signals, and high-speed digital circuitry.
