Teledyne LeCroy ZS2500 Active Voltage Probe

The Teledyne LeCroy ZS2500 is a 2.5 GHz active voltage probe engineered for high-speed signal acquisition where minimal circuit loading and signal fidelity are paramount. Its 1 MΩ input impedance and 0.9 pF input capacitance minimize loading effects on the circuit under test, preserving measurement integrity. The probe delivers an input dynamic range of ±8 V with offset capability to ±12 V, accommodating diverse measurement configurations across 4 GHz and lower bandwidth oscilloscopes.

Designed around the ProBus interface, the ZS2500 integrates directly with compatible Teledyne LeCroy platforms, enabling automatic setup and instrument control. The compact form factor and 1.3 m cable length facilitate access to challenging measurement points. A comprehensive accessory suite - including multiple tip styles, flexible leads, right-angle adapters, and grounding options - addresses varied probing geometries while suppressing ground loop inductance.
