Magnetic field probes for large, medium, small and electric field probes are mainly used for EMI space radiation rectification. Mainly used for magnetic field radiation testing. Probes that can identify the direction of the magnetic field. The type II magnetic field probe adopts a semi-shielded structure. Three sides of the magnetic field induction coil are shielded with copper skin, and one side is exposed to the air. Operating bandwidth of large, medium and small magnetic probes: 1MHZ-7ghz Measured frequency response diagram (large, medium and small) (1MHZ-7ghz) Specification: Style 1 Extra large (type II): handle thickness is about 2.3mm, probe width is about 5.5cm, total length is about 10cm. Style 2 Large size (type II): handle thickness is about 2.3mm, probe width is about 2.5cm, total length is about 10cm. Style 3 Medium size (type II): handle thickness is about 2.3mm, probe contour width is about 1.6cm, total length is about 10cm. Style 4 Small size (type II): handle thickness is about 2.3mm, probe contour width is about 1.0cm, total length is about 10cm. Style 5 Electric field probe (non-contact): handle thickness is about 2.3mm, probe length is about 10mm, total length is about 10cm. Package Includes: 1/5 Piece EMC EMI Near Field Probe(as picture show) Note: Please allow slight dimension difference due to different manual measurement.
