LeCroy HVD3102 High Voltage Differential Probe, 25MHz

The Teledyne LeCroy HVD3102 is a high-voltage differential probe engineered for precision measurement of differential signals in the presence of large common-mode voltages. Operating at 25 MHz bandwidth with 1 kV CAT III safety rating, it delivers 1% gain accuracy and exceptional CMRR across a broad frequency range - critical for power electronics characterization and control signal isolation on high-voltage buses.

• Cable length: 2250 mm (88.583 inches)


• Safety certification: 1 kV CAT (CAT III 1000V)

Key Features

• ProBus active probe interface with automatic scaling - eliminates external power supply requirements


• AutoZero with auto disconnect switch for calibration of offset drift without probe removal


• Wide oscilloscope compatibility across Teledyne LeCroy platforms equipped with ProBus and XStream software v7.4 or greater


• Dual attenuation modes for measurement flexibility from millivolt to kilovolt scales

Typical Applications

• Control signal measurement on high common-mode voltage buses


• Switch-mode power supply analysis (120/240 V)


• 600 V and 5 kV class apparatus characterization

Compatibility & Integration The HVD3102 integrates directly with any Teledyne LeCroy oscilloscope supporting the ProBus active probe interface. Automatic probe detection and scaling eliminate manual configuration. Certification to IEC/EN 61010-031:2015 and IEC/EN 61326 ensures safety and EMC compliance.
