As the world works on developing renewable energy resources, one growing challenge is how to have enough battery energy storage systems (BESS) to support the increasing number of electric vehicles (EVs) and the evolving smart grid. Surprisingly (or not), the humble school bus is emerging as a great candidate in the drive toward a low-carbon grid. It starts with a vision to lower carbon emissions by switching from diesel-powered to electrified fleets. Upgrade old school buses to zero-emission m...
Following the introduction, earlier this year, of the first test solution for authentic validation of zero trust networks, Daniel Munteanu, the Product Manager at Keysight, is extremely excited to take this opportunity to provide more information about this major milestone that is shaping the future of network application and security testing. Typically, for a product, a 2.0 release marks the transition into the maturity stage (or, even a brand-new initiative), but with CyPerf 2.0 it is more th...
A study by EMA - Enterprise Management Associates, found that 66% of organizations do not have the network visibility they need. And 79% of enterprises believe it is important to establish an end-to-end visibility architecture for physical on-premises and hybrid cloud deployments. The study stresses the importance of how data points for network visibility provides security and monitoring tools the data they need to secure networked applications. Keysight Vision E400S network visibility solutio...
Most technology currently is wireless or nearly wireless. The majority of wireless systems use multiple antenna techniques at the transmitter, receiver, or both to enhance system performance in commercial or aerospace and defense applications. Multi-antenna techniques include antenna diversity, multiple-input / multiple-output (MIMO) spatial multiplexing, beamforming, and phased-array radar. Radio-frequency (RF) engineers use these techniques to achieve diversity, multiplexing, or antenna gains...
Digital components communicate with different data protocols, each governed by its own standards body. Users might test a circuit board with multiple types of data buses at the same time. The standards bodies regularly update the protocols to accommodate faster data speeds, which often come with more complex compliance test specifications (CTS). Using automated compliance test software Validating a product to new CTS requires time, money, and knowledge to get it to market. One engineer can&rs...
The first and second parts of the 5G signal analysis (spectrum analysis) conformance testing blog series, based on the 3rd generation partnership project (3GPP) standard requirements, discussed base station transmitter characteristics, such as transmit power, output power dynamics, transmit on/off power, and signal quality, that can be measured using a RF spectrum analyzer. This article focuses on unwanted emissions testing as another requirement defined by 3GPP standards, when performing signa...
Efficient sharing of computing and storage resources is critical for data centers and high-performance computing clusters. For this purpose, specialized servers are linked to each other via switches. The first level of connection takes place in the server rack, where servers are interconnected via a top of the rack (TOR) switch using passive and/or active cables. Layer 1 and Layer 2 switches (also called leaf and spine switches) are used to share resources between racks. As they are usually mor...
Demand for high data throughput and low latency is pushing device specifications and operational standards toward wideband modulation. Wideband performance benefits come with a heavy cost: significantly increased noise. Increased noise This noise introduces additional test complexity and measurement uncertainty, which is further exacerbated by the industry’s desire to pack as many modulated signals into the available bandwidth as possible. This not only constrains error vector magnitude...

For decades, the semiconductor industry has been struggling with near short defects in the wire bond of an integrated circuit (IC), without an effective solution to detect it. When two wire bonds come very close to each other, but are not electrically shorted, that results in a near short condition. This presents a potential reliability issue. The insulative barrier between the wires can give way over time, or after extended stress, resulting in a catastrophic failure of the device. Depending o...
Organizations today are faced with growing challenges, when it comes to defending against increasingly sophisticated cyber-attacks. Ransomware, software supply chain attacks, denial of service, malware, botnets, social engineering – a seemingly infinite list of attack techniques are upping the ante and driving security teams to burnout. Attackers have at their disposal a plethora of known Common Vulnerabilities and Exposures (CVEs), as well as unknown zero-day techniques. complexity of e...
Ultra-reliable low latency communication (uRLLC), massive MIMO, phased arrays - The implementation demands of 5G FR2 are propelling revolutionary transformation in communication technology. While normalized loads and linear behavior are every amplifier designer’s dream, massive MIMO and beam-forming architectures experience highly variable load conditions in practical applications. 5G FR2’s mmWave carrier frequencies Further complexity is added with 5G FR2’s millimeter wave...
With standards constantly evolving, test solutions must support higher frequencies, wider bandwidths, and new physical layer capabilities. The daily lives are enhanced by a variety of innovative and comprehensive mobile wireless communication applications thanks to the much faster, more reliable, and near-instant connections that come with the 5G. To ensure that base stations live up to their promises, they must also pass new conformance tests. Conformance testing is an essential part of the ba...
5G’s foray into the industrial world starts with the development of standards. 5G private networks also require government involvement for spectrum and civilian and military applications, and from industry for trials, testbeds, and ecosystem solutions. Many industry organizations participate in the development of standards for 5G private networks. The most notable ones are the 3rd Generation Partnership Project (3GPP) and the 5G Alliance for Connected Industries and Automation (5G-A...
Electronic devices are increasingly power-hungry. Consumers are demanding more functionality and features from everyday electronics. To meet this demand, engineers build devices that do more than ever before. These devices consume more power to fuel the new capabilities. Overvoltage (OV) and overcurrent (OC) are important security features in power supplies. Using these features lets users protect the device under test (DUT) from a higher voltage than the DUT’s design was meant to handle....
The article “The ABCs of Lithium-Ion Cell Manufacturing” provides an overview of the lithium-ion cell manufacturing process. In the article the author walked through 10 main steps of the manufacturing process, starting with preparing the materials that go into the cell’s construction and ending with final testing and grading. While these 10-steps are comprehensive, manufacturers are always looking at ways to enhance their process to better suit their specific needs. One way to...
The automation trend is pushing more functional tests (FCT) systems into automated inline platforms. We are seeing increasing requests of automated inline functional test solutions. Functional test solutions consist of specific test requirements. Every solution uses a combination of instruments and test loads. It is not difficult to create an automated inline handler for a specific functional test setup. However, these kind of handler systems are unique and non-generic. This is good for s...
