Our professional emc testing equipment is designed to meet every standard mentioned.
Open Area Test: The OATS test is designed to simulate the normal usage conditions for an electronic device as closely as possible. This procedure takes place in an area with no metallic materials other than the emc test equipment. The results are recorded by a noise level meter, which detects the level of EMI produced. This open field test is best suited for finished electronic products and often requires specialized emc testing equipment to ensure environmental variables are accounted for. When setting up the site, technicians calibrate their emi testing tools to capture accurate noise levels.
Shielded Box Test: The shielded box technique employs a sealed box with a cut-out portion. A conductively coated shielding unit is placed over the box’s opening, and all transmitted and received emissions are measured using various emi testing tools. The electromagnetic signals from both inside and outside the box are recorded and compared, with the ratio between the signals representing shielding effectiveness. To achieve precise results, the emc test equipment must be properly coupled with the box interface. This method allows for a controlled environment where emc testing equipment can measure the specific performance of the shielding material.
Shielded Room Test: Architectural EMI shielding is used to reduce the amount of ambient noise in an area, necessitating a shielded room technique. In this setup, the testing device and the emc testing equipment are placed in one room. This shield room process is well suited for evaluating a device’s susceptibility to interference. By utilizing internal emi testing tools, researchers can isolate the device from external electronic noise. Furthermore, the emc test equipment remains protected from outside signals, ensuring the integrity of the susceptibility data.
Attenuation and Effectiveness: Attenuation is one of the principal indicators for measuring the effectiveness of electromagnetic interference shielding. The level of attenuation for an EMI shield complex, and the methods used to retrieve the results, often vary according to the particular shielding application.
