So, what is the primary use of an shielding box?
Everyone has heard of wireless technologies like Bluetooth, Wi-Fi, and GPS, and has likely purchased wireless products such as mobile phones or Bluetooth earphones. When these products are first designed, it's crucial to ensure the integrity of signal transmission and reception. Instruments are needed to verify whether the signals are correct, comply with regulations, and meet the expected specifications. However, there's an environmental issue: since the air is already filled with various wireless signals, the signals picked up by the instruments during testing can be interfered with. This is where the shielding box comes into play. When the product is placed inside the isolation box for testing, external signals are prevented from entering, ensuring that all signals received by the instruments are purely from the product itself.
