The LeCroy DXC200 is a passive differential probe pair engineered for high-fidelity differential signal measurements with minimal capacitance loading. This x1 attenuation probe pair integrates with Teledyne LeCroy DA1800 series differential amplifiers to deliver full gain and Common Mode Rejection Ratio (CMRR) performance at the probe tip, enabling 100 MΩ input resistance measurements across demanding test environments.
