The Langer EMV-Technik GmbH RF Passive Near-Field Probe Series (30 MHz to 3 GHz) is designed for high-frequency EMC diagnostics and troubleshooting of electronic circuits. These passive probes enable precise detection and localization of RF interference sources on PCBs, cables, and components. Optimized for use with spectrum analyzers and oscilloscopes, the series supports both electric-field and magnetic-field measurements, offering high spatial resolution for detailed emission analysis from broad-area scanning to fine fault isolation.
