Testing and measurement: T-Mo tout umlaut testing



Testing firm umlaut evaluates US 5G networks, according to a new report.

Up to 1,000 points on the umlaut scale, T-Mobile US ‘5G scored 724, compared to AT & T’s 569 and Verizon’s 555.

T-Mo scored particularly well in coverage and reliability to support that highest overall scoring, while Verizon achieved the best scoring for network latency. “Our 5G network is providing a level of performance, coverage and reliability that our competitors do not match. And that experience will only improve for customers when we accelerate the construction of this amazing network! ” Neville Ray, president of technology at T-Mobile US, said in a statement Highlight umlaut’s test.

Umlaut’s test was based on device-based test crowdsourced data that works in the background for data collection, combined into about 1,300 smartphone applications. The company said its findings were based on 3 billion data samples collected over a 24-week period from November 2021 to this month, representing about 600,000 5G-enabled users.

– Pushing higher in the radio frequency spectrum, KeySite Technologies Announced this week that it has teamed up with three other companies to make a new offer Broadband vector network analysis solution Which supports on-wafer millimeter-wave component characterization of devices and circuits, with the goal of accelerating the development and design of 5G and emerging 6G systems. The results of a joint VNA solution test and collaboration with a measurement technology company Form factorMillimeter-wave and terahertz probe developer Dominion microprobes And Virginia diodes (VDI), which designs and manufactures mmWave and terahertz devices, components and systems.

“We’ve worked closely with Dominion Microprobe in Probe Design and our solution partners, VDI and FormFactor, to provide maximum performance 170 and 220 GHz single-sweep solutions for on-wafer devices and circuit testing,” said Joe Rickert, VP and GM at KeySite. Research and development. “Keysight’s new solutions will enable customers to shorten the design and verification cycle for 5G and emerging 6G applications and allow them to quickly deliver new solutions to the market.”

Rohde and Schwartz Is Offering two new millimeter-wave options For its SMW200A signal generator series which pushes the power of the device up to 56 and 67 GHz.

“Over the past decade, the ceiling for a unique vector signal generator capable of generating complex digitally modulated signals with high precision has been 44 GHz,” the testing company said in a release. “Higher frequencies are only possible with additional external frequency upconverters or lower accuracy, both have limitations.” R&S says the new options bring “previously impossible high performance” to this range of signal generation. The option up to 56 GHz covers all 5G frequencies currently in use, plus earth-to-satellite applications, the company supports the 100 kHz to 67 GHz option designed high frequency 5G band, 60 GHz WiGig band and inter-satellite.

Inside Launched New design-to-test analytics software It is called DataStudio, which says “bridges critical data across semiconductor design and test workflows.”

The first DataStudio application is its Specification Compliance Manager (SCM), which “manages device specifications, connects measurement data sources and automatically generates compliance reports,” NI said, as well as providing device with target specification. “By laying the foundation with a comprehensive data infrastructure, engineers gain clear and effective insights to improve productivity and reduce the manual effort required during chip development,” the testing company said.

NI is also launching a DataStudio Bench Data Connector (BDC) validation bench test library.

“The last few decades have focused on design and testing automation, which generates a lot of data. Our customers want to use this data for better project visibility and decision making, “said Ritu Favre, VP and GM of NI’s semiconductor and electronics business unit.” We are at a tipping point. The amount of data and the pressure to use that data Customers are now looking for solutions to work across the entire stream. “

“With simulators today, it’s hard to say where the problem is with semiconductor prototypes if they don’t meet all the features. Is it a specific part that is flawed? Was it something in the manufacturing process that wasn’t right? Is it a fundamental design flaw?” Ritu goes on. “To debug this, engineers must work against these different silos, using different tools, including different data sets from different vendors. We are breaking down those barriers. ”

NI has also unveiled a new maintenance offer as a service for monitoring and predictive maintenance of test equipment and facilities. ActiveAptime involves monitoring and assisting a dedicated NI technician remotely, and the offer “enhances user capabilities so that predictions can be made before disruptions occur,” says NI.

Testing companies say equipment failure is responsible for 42% of unplanned downtime costs and costs manufacturers ক্ষতি 50 billion annually worldwide কিন্তু but more than half of manufacturers say they use spreadsheets to monitor and manage equipment.

Josh Mারller, SVP and GM of NI’s Portfolio Business Unit, said, “One of the major challenges facing manufacturers is having visibility in physical systems to keep them running smoothly and to avoid the failure of any reputable product.” “ActiveUptime provides the most accurate picture of these systems. With the help of our maintenance experts, our customers quickly get to the root of the problem, get a quick resolution and implement measures to prevent it from happening again.

“Predictive maintenance and status monitoring are becoming key pillars of the broader digital transformation of production,” Muller explained. “Real-time continuous monitoring maximizes total resource uptime, reduces overhead costs, and optimizes maintenance costs by shifting from time-based to user-based maintenance.”
