It is necessary to test electronic equipment that receives radio frequency signals to make sure they comply with applicable regulations and/or business needs. The emission of radio frequency signals is ubiquitous in modern society. These could obstruct the testing and measurement of equipment. As a result, while testing, safeguarding these devices from such interference is essential. The answer to this issue is RF-shielded test enclosures.
Mobile phones, base station transceivers, wireless semiconductors, WLAN/Bluetooth/ZigBee/WiMAX devices, and vehicle multimedia are just a few of the products that may be tested using RF-shielded test enclosures, often known as RF shield boxes.
When deciding which RF shield box to buy, the following features are often the most crucial:
Shielding Characteristics
The RF shield box must offer enough shielding attenuation over a range of frequencies. This is a component that affects the price. Knowing the attenuation requirements can help you choose a box that satisfies your demands while avoiding excessive expenses
Price
Price is often the most noteworthy aspect, provided the box satisfies the shielding criteria. The material used to make the box has an important impact on the pricing. Copper and stainless steel are the two most frequently used materials.
Unless there are extremely stringent attenuation requirements, lab boxes are normally made of stainless steel.
Copper provides higher attenuation, but at a price. Copper is more resistant to oxidation and corrosion. Copper is therefore the best material for outdoor settings.
Ease of use
The ease of use of the RF-shielded enclosure is a feature that is simple to overlook when purchasing, but it can have an important impact on the test procedure, particularly when hundreds (or thousands) of devices need to be evaluated.
