Teledyne LeCroy ZS4000 Active Voltage Probe, 4.0 GHz, 0.6 pF, 1 MOhm

The Teledyne LeCroy ZS4000 is an active voltage probe engineered for precision measurement of high-speed signals in demanding signal integrity applications. Operating at 4.0 GHz bandwidth with 0.6 pF input capacitance and 1 MOhm input resistance, it minimizes loading effects on the device under test while preserving waveform fidelity. The 10:1 attenuation ratio and low capacitive signature make this probe ideal for high-frequency digital design verification and signal characterization on compatible Teledyne LeCroy oscilloscope platforms.
