HT03 is a simple magnetic field near-field probe set that primarily measures signals by receiving electromagnetic field strength. It can be brought close to the target under test (even precisely to IC pins and specific traces) to detect the direction and strength of the magnetic field on the device surface. Used with a spectrum analyzer and other equipment, it effectively helps engineers locate electromagnetic leakage points and determine the causes of interference, making it a practical tool for EMI troubleshooting and remediation. Mainly used for radio spectrum testing, EMC/EMI pre-compliance testing and radio equipment R&D. In EMI troubleshooting, engineers can use it with a spectrum analyzer and preamplifier for targeted frequency band scanning to find and locate noise sources (such as modules, IC pins and specific traces) and propagation paths (such as magnetic field coupling channels). It can also be used to detect the direction and strength of the magnetic field on the device surface, assisting in adjusting connector or display positions to verify the effectiveness of remediation measures.
