Teledyne LeCroy DL10-ISO High Voltage Optically Isolated Probe, 1 GHz

The Teledyne LeCroy DL10-ISO is a 1 GHz bandwidth, optically isolated differential probe engineered for high-voltage signal measurement in common-mode dominated environments. Designed specifically for wide-bandgap semiconductor characterization—GaN and SiC devices—this probe delivers 1.5% system accuracy when paired with Teledyne LeCroy 12-bit HDO oscilloscopes. Its 160 dB CMRR and exceptional common-mode voltage range to ±60 kV (DC+Peak AC) enable reliable measurements in power electronics, automotive, and motor drive applications without loading the Device Under Test.
