Anritsu launches differential noise figure measurement option for VectorStar VNAs
NEW DELHI: Anritsu Company said that it has launched the industry’s first solution capable of conducting extensive characterization of the differential noise figure of differential devices used in high-speed wireless communication systems.
The solution, which integrates a new differential noise figure option into the Anritsu VectorStar vector network analyzers (VNAs), allows R&D engineers to verify the receiver performance of low noise amplifiers (LNAs) and other devices used in the front-end of 5G and microwave back haul systems. The option is available on VectorStar models operating from 70 kHz and up to 20 GHz, 40 GHz, 70 GHz, and 110 GHz.
The new differential noise figure option enhances the 2-port single-ended noise figure measurement capability of the VectorStar and allows the VNAs to measure 3- and 4-port devices in single-ended, differential and common mode operation with a variety of processing options.
The Anritsu differential noise figure option incorporates the similar cold-source measurement technique as its 2-port method, which minimizes mismatch errors for improved accuracy compared to the conventional Y-factor noise source method.
The new enhanced noise figure option adds the ability to perform levels of vector correction in 2- and multi-port devices for greater accuracy particularly, when mismatch is significant.
Measurement analysis of both correlated and uncorrelated noise can be conducted with the new differential noise figure technique. The result is more comprehensive characterization of actual device performance for greater design confidence. It is a superior method than conventional approaches that include an RF balun with only an S-parameter description or neglect correlation between device under test (DUT) output ports, which lead to improper characterization of differential devices. As operating frequencies continue to rise due to 5G, the ability to more accurately characterize device performance will take on added importance.
Accuracy is further ensured by the extended range of network tools for VectorStar. For example, the VNAs have the ability to embed or de-embed single-ended and differential probes and other networks during the on-wafer noise figure measurement process and correct receiver calibrations for other setup changes. The result is more accurate noise figure characterization of differential devices in an on-wafer environment.
The MS4640B VectorStar VNAs have the broadest coverage in a single instrument, 70 kHz to 70 GHz. Coverage can be extended to 145 GHz and 1.1 THz in broadband configurations. VectorStar is the only VNA platform capable of measuring noise figure, both single-ended and differential, from 70 kHz to 125 GHz.
The MS4640B VNA series offers a new level of performance for device modeling engineers struggling to accurately and reliably characterize their devices, for R&D engineers pushing the last fraction of a dB out of their state-of-the-art designs, and for manufacturing engineers who must maximize throughput without sacrificing accuracy.
NEW DELHI: Bharti Airtel, India’s telecommunications services provider, today announced the launch of its ultra-fast 5G services in 125 cities. Airtel 5G Plus service is now available to customers in over 265 cities in the country.
Airtel 5G Plus has three compelling advantages for customers. First, it runs on a technology that has the widest acceptance in the world with the most developed ecosystem. This ensures that all 5G smartphones in India seamlessly work on the Airtel network. Second, the company promises to deliver the best experience – between 20 to 30 times higher speeds than today coupled with brilliant voice experience and super-fast call connect. Finally, Airtel 5G Plus network will also be kinder to the environment with its special power reduction solution. Powered by the reliable Airtel network infrastructure, Airtel 5G Plus will provide superfast access to High-Definition video streaming, gaming, multiple chatting, instant uploading of photos et all.
Commenting on the launch, Randeep Sekhon, CTO, Bharti Airtel said, “5G has revolutionized the world of internet, ushering new era of connectivity and communications that will prove to be a game-changer for the country. At Airtel, we remain committed to delivering the highest quality of network and service to our customers as we roll-out 125 more cities today. Airtel was the first in the country to offer 5G services in October 2022, and today’s mega launch is our promise to connect every Airtel customer in the country with ultra-fast Airtel 5G Plus. Our 5G rollout is on track to cover all towns and key rural areas by March 2024.”
Airtel 5G Plus service availability will continue to rapidly expand – including service in all towns and villages in the country soon – as the company is working towards offering nationwide coverage. Airtel is now offering its 5G services in every major city from the upper northern city of Jammu to the southern tip of Kanyakumari.
In the last one year, Airtel has demonstrated the power of 5G with a host of powerful use cases that will change the way customers lead their lives and do business. From India’s first live 5G network in Hyderabad to India’s first private 5G network at the BOSCH facility in Bengaluru to partnering with Mahindra & Mahindra to make its Chakan manufacturing facility, India’s first 5G enabled auto manufacturing unit, Airtel has been at the forefront of 5G innovation.
NEW DELHI: Apple Inc has rolled out a beta programme to enable 5G on Apple devices as the upgrade lets users try out pre-release software.
This software upgrade enables 5G access on Apple devices, as and when service providers Jio, Airtel and Vodafone enable 5G network access, sources said.
Apple Users have to enrol for the Beta Programme on the website, install a profile and download the software.
Jio users using iPhone 12 and above, in cities where JioTrue5G has been rolled out, will be invited to the Jio Welcome Offer. Jio Welcome Offer provides unlimited 5G data at up to 1 Gbps speed to users at no additional cost. However, there is a condition that prepaid users must be on active Rs 239 and above plan. All Postpaid users are eligible for this trial.
Airtel is not providing any special 5G offer like Jio to their users. In the cities/areas in which the Airtel 5G network has been launched, users can trial 5G services as a part of their existing plan, once they have updated the latest Apple Beta software.
While an email sent to Apple did not solicit an immediate response, the firm had last month stated: “We are working with our carrier partners in India to bring the best 5G experience to iPhone users as soon as network validation and testing for quality and performance is completed. 5G will be enabled via a software update and will start rolling out to iPhone users in December”.
Airtel and Jio customers on iPhone 14, iPhone 13, iPhone 12 and iPhone SE (3rd generation) models can experience 5G as part of Apple’s iOS 16 Beta Software Program. The Apple Beta Software Program is open to anyone with a valid Apple ID who accepts the Apple Beta Software Program Agreement during the sign-up process.
If a user has an iCloud account, that is an Apple ID, it is recommended they use that. If they do not have an iCloud account or any other Apple ID, they can create one.
Customers who want to try the beta software should back up their iPhones before installing the beta software. It is recommended to install the beta software only on non-production devices that are not business-critical. Users can also provide feedback to Apple on quality and usability, which helps Apple identify issues, fix them, and make Apple software even better.
The iOS beta comes with the built-in Feedback Assistant app, which can be opened from the Home screen on the iPhone or iPad or from the Dock on the Mac.
