330130-075-00-05 Near field probe is an important tool that can simultaneously measure and detect electric and magnetic fields of objects, which is widely used in wireless communication, radio frequency technology, electronic equipment testing and medical fields.
Near-field probes have a wide range of applications in several fields, including but not limited to the following scenarios:
Wireless communication test: The near-field probe can measure the radiation power and frequency emitted by wireless communication devices. This is very important to ensure signal quality, reduce electromagnetic pollution, and ensure equipment safety.
Electromagnetic compatibility testing: Near-field probes can perform electromagnetic compatibility (EMI) tests on electronic devices to detect whether the device interferes with other devices or is subject to external interference. By testing electromagnetic radiation and conducted signals, the anti-interference ability of the equipment can be evaluated, and the reliability and stability of the equipment can be improved.
Troubleshooting and analysis: Near-field probes can be used for troubleshooting and analysis to quickly locate and diagnose electromagnetic faults by measuring radiation and conducted signals. For example, on a circuit board, the location or cause of the fault can be determined by detecting changes in the signal, so that repairs or improvements can be made.
Electromagnetic radiation protection: Near-field probes can be used to evaluate, design and improve electromagnetic radiation protection schemes. By measuring the intensity and frequency of electromagnetic radiation, it is possible to determine which parts need enhanced shielding measures, thereby reducing the risk of exposure to electromagnetic radiation in the environment.
Medical field: The near-field probe can also be used for bioelectrical signal detection and research in the medical field. By placing the near-field probe near the human body surface, the electrophysiological signals inside the human body can be monitored and recorded in real time, such as electrocardiogram, electroencephalogram, etc. The analysis and study of these signals are of great significance for the diagnosis and treatment of diseases.
