T6290U service objectives

In June 22, the 5G R17 standard was announced to be frozen. It marks that 5G technology and standards have entered a stable period, and the preparation of R18 standard of '5.5G' has started. At the same time as the evolution of cellular technology standards, IoT applications have also driven the continuous evolution of non cellular related standards. Short distance communication technologies, such as Wi Fi, Bluetooth and UWB, can be closely combined with the subdivided IoT scenarios according to their own characteristics to provide users with a better service experience.

IoT modules, CPE and intelligent devices are supporting more and more technologies and standards, which brings many new challenges to RF testing and measurement, especially the relevant testing requirements of 5G, Wi Fi and UWB. The flexibility of 5G technology has spawned a wide range of complex terminal equipment. For manufacturers, the testing of 5G equipment is a huge challenge; As far as WiFi technology is concerned, WiFi 6/7 can meet the requirements of multi-user high-speed communication at the same time through greater bandwidth (320 MHz), higher frequency band (up to 7.125GHz), higher modulation mode (4096 QAM), more antenna numbers (up to 16 groups), and more efficient resource allocation mode (OFDMA), which further increases the test difficulty; Due to the extremely short pulse duration and the bandwidth used by UWB is above 500MHz, the required test solution for designing, integrating and testing broadband radio equipment under low power conditions needs to be able to generate and analyze a wide range of signals and have the necessary dynamic range.

It can be seen from the above technical development trends that in 5G, Wi Fi, UWB and other communication fields, the application frequency band has expanded the signal working frequency band to a higher level. At the same time, the signal bandwidth has gradually increased from 100MHz/160MHz to 500MHz or even 2GHz, and the RF indicators of the signal (including phase noise, EVM, spurious, etc.) have become more important.

In order to address these high-end requirements and complex technical challenges, advanced RF testing solutions are essential, and the requirements for capacity utilization and flexibility need to be considered at the same time.
