Fiber Optic Isolated Voltage Probe. GEVP
The Gate Explorer Voltage Probe ® is a modular fiber isolated voltage probe that allows power electronic engineers to measure floating gate voltages from semiconductors, floating current shunts or bipolar junctions with the advantages of fiber isolation. Two input ranges enable the measurement of low level signals riding in rapidly varying common modes, all with an exceptional CMRR, something that is not possible with differential probes. The probe is USB powered, supports tripod mounting to minimise common mode capacitance and connects to any oscilloscope with a BNC input.
The probe features a touch protected SMB input connector, 10kVrms isolation and external cable accessories to make DUT to probe connections.
