Teledyne LeCroy ZS1000 Active Voltage Probe, 1 Ghz, .9 Pf, 1 MOhm

The Teledyne LeCroy ZS1000 is a 1 GHz active voltage probe designed for high-frequency measurements with minimal circuit loading. It delivers a 1 MΩ input resistance and 0.9 pF input capacitance for exceptional signal fidelity in sensitive measurement applications. The probe integrates with Teledyne LeCroy oscilloscopes via the ProBus interface, enabling automatic scale factor adjustment and front-panel control without manual rescaling. Its 10:1 attenuation ratio and ± 8 V input dynamic range support voltage measurements up to 20 V maximum input without damage. The probe’s low input impedance of 354 Ω at 500 MHz—compared to 34 Ω for equivalent passive probes—reduces circuit loading while maintaining measurement accuracy across complex electronic systems.
