Bluetooth headset RF test


JiaWeiHua is a professional bluetooth headphone manufacturer, offers custom bluetooth headphones. Our bluetooth headset products have been RF tested.


Radio Frequency, referred to as RF. Radio frequency is radio frequency electric current, it is a kind of abbreviation of high frequency alternating current changing electromagnetic wave. The alternating current that changes less than 1,000 times per second is called low-frequency current, and the one that changes more than 10,000 times is called high-frequency current. Radio frequency is such a high-frequency current.


Let's first understand the principle of RF: RF products are deliberately launched, and RF products use a certain frequency range to transmit useful signals, so as to achieve the purpose of transmitting information. In addition to the useful signal, different levels of harmonic signals are generated, so the useful signal (main frequency) and harmonics must be restricted. Including Output Power, Power Density, Bandwidth, Frequency Error, Spurious Emissions, etc.


Let's take a look at the importance of RF testing: When wireless products are to be sold in the European Community members, certain details must be considered. Since the EU member states have developed independently in history, the frequency bands opened by each country may be different, so in the EU area, some frequency bands still need to be unified. Fortunately, at the same time, there are many frequency bands that have been hormonised in the old EU member states. However, those wireless products that are clearly intended to be used outside the harmonised frequency band (the so-called Class 2-equipment) must pass the prescribed filing procedures. After filing, the equipment wholesaler (or manufacturer) informs the frequency management authority of the member country that the product intends to be marketed in that country. The competent authority has 4 weeks to raise an objection. If there is no objection during this period, it means that the product can be marketed in these countries. The product, packaging and documentation attached to the product must clearly state the operating restrictions.


To sum up, you must have an understanding of the nature and importance of RF testing. In order to better ensure the quality and quality of products and meet the access requirements of the international market, bluetooth headphone manufacturers use the latest version of RF testing. instrument. It should be reminded that not all Bluetooth headset manufacturers have these devices, so partners should not just look at the price when looking at Bluetooth headset products.
