1. Brief description of product use: test card, test card, - card, - card, test card, test card, test card, R test card, mobile phone test, test card, test card, mobile phone test card (also known as white card), use Signal testing for communication industry production (Long-term evolution) is a long-term evolution of technical standards formulated by 3 organizations. The project was officially established and launched at the Toronto meeting on March 3, 2019. The system introduced key transmission technologies such as multi-antenna and multi-antenna, significantly increasing It improves the spectrum efficiency and data transmission rate (the peak rate can reach uplink b/, downlink b/), and supports a variety of bandwidth allocation: .3 and etc., the spectrum allocation is more flexible, the system capacity and coverage are significantly improved. The wireless network architecture is flatter ization, reducing system delay, network construction costs and maintenance costs. The system supports interoperability with three other systems. - It has become the most widely adopted standard in countries and regions in the world and has the richest types of terminals. .). Commonly used in mobile phones, mobile phones, mobile phones, mobile phones, mobile phones, R mobile phones, mobile phones, with comprehensive testers and self-built networks to conduct interference-free comprehensive testing of mobile phones. Mobile phones require relevant signal testing of finished products during production, but large-scale A poor screen requires more manpower, material resources and test time, which complicates the production process and increases costs. The test card can realize the only path from the signal to the instrument to the mobile phone, making the test environment more concise and well solving this complex problem. question. The test card can be used for coupling testing, bit error rate testing, and has complete functions and can be used for terminal and comprehensive tester testing.
2. Brands of testing instruments that the product is suitable for:
Suitable for various foreign and domestic testing instruments such as Agilent, Anritsu, Rohde, Schwarz, Galaxy Highlights, etc. Networks built by mobile phone manufacturers or operators themselves, etc.
