The Teledyne LeCroy HVD3605A is a high-voltage differential probe engineered for precision measurement of differential signals in demanding power electronics environments. Operating at 100 MHz bandwidth with 1% gain accuracy and exceptional common-mode rejection, it delivers clear signal acquisition in high-noise conditions. The probe supports floating measurements up to ±7600 V (DC + peak AC) with dual attenuation settings, making it suitable for applications spanning 120/240 V switch-mode power supplies through 5 kV class electrical apparatus. Safety-rated to 6 kV CAT with 6000 Vrms continuous capability and 8485 V peak rating, the HVD3605A integrates via ProBus active probe interface with automatic scaling, eliminating external power requirements.
