'3c' Certification Is 'china Compulsory Certification'. In 3c Certification, Electromagnetic Compatibility Testing Is A Very Important Content, And Standard Emc Testing Uses Far-field Measurement, Which Refers To Emc Darkroom Or Emc Open Field In The Measurement Performed, The Distance Between The Measuring Antenna And The Measured Object Is Generally More Than 3 Meters, And The Result Given Is A Spectrum Diagram, That Is, The Electromagnetic Radiation Intensity At Each Frequency Point. Far-field Measurement Results Cannot Provide Us With Information About The Location Of Electromagnetic Radiation Sources. Therefore, There Is Blindness When Troubleshooting Electromagnetic Interference.

The Near-field Measurement Of Electromagnetic Fields Refers To The Measurement Of Near-field Probes Near Electronic Products. In Addition To Giving A Spectrogram, Near-field Measurement Can Also Provide Information About The Spatial Distribution Of Electromagnetic Interference, That Is To Say, It Can Locate Electromagnetic Interference Sources And Propagation Paths. In Order To Quickly And Accurately Locate Electromagnetic Interference Sources, Effectively Eliminate Electromagnetic Interference Problems, And Enable Products To Pass The Emc Far-field Test As Soon As Possible, Emscan Launched The 'electromagnetic Interference Scanning System' In 1989, Which Can Scan And Measure The Electromagnetic Field Of Electronic Products In The Near Field. , Give The Frequency Spectrum And Spatial Distribution Diagram Of The Electromagnetic Interference Generated By The Measured Object.

If The Product Cannot Pass The 3c Certification Due To Electromagnetic Compatibility Issues, The Use Of Emscan Iv Can Quickly Locate The Problem And The Cause, Paving The Way For The Product And The Morning Market.

In Order To Help Engineers See The Electromagnetic Field Clearly, Rongxiang Introduced This Product From Emscan In Canada, And Rongxiang Is The Agent Of Emscan's High-speed Electromagnetic Interference Scanning System-emscan Iv.
