Magnetic field probe HNFP series

for spectrometersfor spectroscopyreal-time

The HNFP series of near-field probes cover the 9KHz to 3GHz frequency range and are ideal for use in the development of cost-effective EMI troubleshooting solutions, which can be employed to address a wide range of EMI problems. The product comprises seven probes designed to test magnetic fields (H) and two high-frequency probes designed to test electric fields (E). The magnetic field probes feature special electrically isolated probe heads with varying head shapes, offering versatility for near-field measurement tasks. All near-field probes are passive and are connected directly to a spectrometer or oscilloscope via a 50Ω cable, allowing for real-time magnetic field testing and analysis. In situations where the interference signal is weak, our 30dB gain pre-RF amplifier (HNFPA-1) can enhance the system test sensitivity. Facilitate the identification and resolution of potential EMI/EMC issues prior to product release for conformance testing. - High-frequency magnetic field probes frequency range: 30MHz-3GHz; Low-frequency magnetic field probes frequency range: 9kHz-50MHz; - High-frequency E-field probes frequency range: 30MHz-3GHz; - HNFPA-1 preamplifiers frequency range: 9kHz-3GHz, with a gain of approx. 30dB; - All near-field All near-field probes are passive and can be plugged into the input port of an oscilloscope, receiver or spectrum analyzer; - Large loops are more sensitive but have lower spatial resolution, while small loops are less sensitive but make it easier to narrow down the location of the source; - Magnetic-field probes contain special electrically isolated probe heads, with different head shapes to suit different near-field measurement tasks;
