1.Summary

EM5030/EM5030LF series probe set contains 7 probes specially designed for testing magnetic field. These probes are used to locating the interference source in EMI pre-compliance debugging and can effectively shield the interference from electric field. EM5030’s frequency range is between 30MHz~3GHz, and it has 4 types of probe head shapes.EM5030LF’s  frequency range is 9kHz~50MHz, with 3 types of probe head shapes.

The probe is directly connected to the spectrum analyzer or oscilloscope with 50Ω BNC cable. When the radiation or the conduction disturbance of the product surpass the standard, users can use the near field probe to search for the certain component or circuit generating the interference of certain frequency by measuring the coupling channel between the module and the signal shifting speed, RF voltage of the evaluating system. When the interference signal is relatively weak, users can improve the system sensitivity with the EM5020A(20dB attenuation) or EM5020B(30dB attenuation) pre-amplifier.
