The Langer EMV-Technik GmbH LF passive near-field probe series (100 kHz to 50 MHz) is a range of high-precision electromagnetic compatibility (EMC) measurement tools designed for development and debugging of electronic assemblies. These passive magnetic-field probes are used for near-field emission analysis and allow engineers to localize interference sources on PCBs, cables, and components. The probes are typically connected to a spectrum analyzer or oscilloscope and are optimized for high spatial resolution, shielding, and flexible measurement distances.
