Keysight (Agilent) 10076B High Voltage Probe, 100:1, 4 kV, 250 MHz

The Keysight (Agilent) 10076B is a passive high-voltage probe designed for precision measurement of high-voltage, high-frequency signals across laboratory and field environments. With a 100:1 attenuation ratio and 250 MHz bandwidth, it captures fast transients and complex waveforms with minimal signal distortion. The probe handles up to 4000 Vpk (CAT I) and delivers sub-1.4 ns risetime performance, making it suitable for switching transient analysis, power electronics characterization, and high-voltage circuit debugging.
