As the wireless communication network faces the 5G future, the test and measurement industry will face major challenges in meeting this change. In order to carry the huge lineup of equipment and applications required by the market, 5G technology will not only be progress, but will usher in a huge leap.
The new 5G ecosystem will be built with technologies that create connections with lower latency and faster, and at the same time be able to connect a larger number of devices than previous generations of technologies. These applications bring very challenging new device requirements, requiring test and measurement equipment to have two key performances:
Œ Measurement performance in a wider spectrum range (including 28 Ghz and 39 GHz millimeter wave)
Perform these measurements with a higher signal-to-noise ratio for bandwidths (>1 GHz) that could not be surpassed in the past
Ready before 5G arrives
Electronic test and measurement always needs to be ahead of the latest technology. When the technology is as disruptive and influential as 5G, gaining and maintaining a leading position often requires establishing strong relationships with suppliers who can be both partners and device providers. As wireless broadband technology continues to evolve from generation to generation, and given that the frequencies used are well known, ETM manufacturers can usually rely on a large number of software upgrades to adapt to changes and impose lower-risk changes on the hardware. As the industry shifts to millimeter wave radio transmission, the migration to 5G will require more advanced solutions. Duncan Bosworth, General Manager of ADI’s Instrumentation Division, said: “Rohde & Schwarz knows that new designs are extremely challenging. Rohde & Schwarz makes full use of the long-term relationship with ADI to ensure that the performance of key components can be maximized.”
Bosworth added: “We shared our ideas with them at the beginning of the design process. We often have discussions and continue to invest in the best people.” This way of cooperation ensures that the goals of the two companies are aligned, which convinces Rohde & Schwarz ADI solutions can meet the high-performance requirements of the project.
Bring test innovation to the market
Rohde & Schwarz has developed the R&S®SMW200A vector signal generator and R&S®FSW signal and spectrum analyzer. Both can achieve high-frequency testing with low background noise, creating value for diversified applications. The two instruments are designed to meet 5G challenges by generating and analyzing wide modulation bandwidth millimeter wave signals up to 2 GHz, far exceeding the noise level required by terminal equipment. These two devices are being tested against the building blocks of next-generation 5G devices, covering millimeter wave frequencies and traditional cellular frequencies below 6 GHz.Both products use ADI’s data converters and RF devices
Help customers solve their customers’ problems
Rohde & Schwarz’s equipment needs to handle higher frequencies and wider bandwidths, which means that ADI’s focus is on RF and converter performance.
With the help of ADI’s converters and RF devices, the R&S®SMW200A vector signal generator can provide an internal baseband modulation bandwidth of up to 2 GHz, which meets the 4th and 5th generation standard requirements. At the same time, the product is designed to meet future needs, with the help of a modular and scalable architecture design, allowing users to optimize the generator according to the application and upgrade when needed.
The R&S®FSW signal and spectrum analyzer uses advanced high-speed converter technology to help provide IF/RF sampling with excellent speed and linearity. This allows R&S®FSW to meet the ever-increasing demand for analysis bandwidth (up to 2 GHz).
Test the future
For Rohde & Schwarz’s customers, to bring a new generation of product concepts to the market, first of all to ensure that they can work properly. This means that the test equipment needs to perform better than the equipment under test. Finding the right specifications in the data sheet is just the beginning. Being able to work closely with suitable suppliers, obtain effective help, and give full play to the effectiveness of their products has a significant impact. Christoph Pointner, vice president of Rohde & Schwarz’s signal generators, audio analyzers and Power meters, said: “We have benefited from strong cooperation and open communication. Therefore, we are confident that ADI can deliver the promised level of performance. It is true. So.” All of this means that Rohde & Schwarz can concentrate resources to create more value for the end customer.
Provide different solutions for different customers
Not all ETM manufacturers have the resources to develop every part of the signal chain. Instead, they may need to rely on the supplier’s products and technology. ADI can provide a very wide range of high-speed converters and RF product portfolios for a new generation of broadband instrumentation, supporting bandwidths up to 4 GHz or more. At the same time, ADI has deep expertise in the ETM market to provide support to customers. Bosworth said: “We not only develop innovative technologies and products, but also look forward to finding innovative ways to help customers use them. Only in this way can we provide a wide range of help. Our system engineering team fills up resources by providing support, services and designing a complete instrument-level signal chain. gap.”
Greet the future together
For many industries, the 5G future is about to usher in. As 5G gets closer and closer, the focus is shifting to the field of electronic test and measurement. Therefore, for ETM manufacturers, 5G has arrived. The unprecedented technology of the 5G ecosystem will increase the demand for ETM products to measure performance in a wider spectrum and to perform measurements over a wider bandwidth.
For ETM companies, meeting the 5G challenge requires not only new products with stronger functions, but also new relationships to make full use of expertise and collaboration. Rohde & Schwarz has the knowledge, abilities and skills required for the 5G market. It can also rely on a partnership with ADI to provide components and support. Rohde & Schwarz is working with ADI to develop leading products to provide reliable measurements for the building blocks of 5G in the future.
