Tips, How To's and Do-It-Yourself's (DIYs) to help you in the measurement and test equipment industry.
What do you know about the wireless standard 802.11ac? This quiz covers the performance and specifications of this technology.
IEEE 802.11ac is taking hold in wireless networks at homes and in public places. How much do you know about its performance and specifications?
Usually, we try to offer news and advice engineers can use, but it's back-to-school season. So today, we turn the tables and ask you: What did you do right in college? and, what would you do differently? You - our clients - have a tremendous amount of knowledge, and even more importantly, real-world engineering experience. Share it, and you'll help improve the future of engineering.
That sounds like a lofty goal, but we're engineers, after all. We aim high and follow through. And while real life doesn’t offer “do-overs,” engineers really understand the value of learning from errors.
Fiber optic components, cable plants and the telecommunication systems that use them can be complex. They are comprised of fiber, connectors, splices, LED lights, laser sources, detectors and receivers—all forming an inter-connected tapestry of technology, each dependent on the next to function properly.
The debate about when to select a logic analyzer or an oscilloscope is one that goes on in labs across the country. On one hand, logic analyzers allow you to capture multiple signals from digital circuits or systems and in some cases, even convert the data into information such as timing diagrams or decodes for protocols. On the other hand, oscilloscopes are tools for observing signal voltages that vary constantly and can also measure non-electrical signals like sound and convert and display them as voltages.
Here's our next news roundup, focusing on a new fiber alternative to data transmission, our favorite Friday quiz, and other interesting topics. Don't forget to check out the MATsolutions Industry News page for weekly information, ranging from tips on equipment maintenance, to purchasing and safety, to useful "how to's" and industry news.
Measuring dielectric properties in materials is an important aspect of improving the design of electrical equipment, as well as the quality and control of insulating conductors and various electronic components. The importance of testing electricity within materials is undeniable, but using the right measurement will ensure you get the right data.
To get a better understanding of dielectric measurement techniques, we've detailed six methods that are commonly used.
Measuring electrical signals at a microvolt level raises the potential for errant readings. Such tiny signals can be easily masked by external factors, including thermal effects and EMI, and internal effects such as crosstalk from other signals on the same board or device. Knowing such obstacles await will give you the opportunity to plan for them and troubleshoot the issues that could arise when taking low voltage measurements.
If you rush into this task like it’s easy, you could be setting yourself up for an accident. Many times, the job of testing and installing itself represents only a small portion of the work that needs to be done. Planning ahead will make the task more efficient and safer not just for the people performing the work, but for everyone else in the working environment.
It’s critical to have confidence in the equipment that you use to measure and test your products and tooling. This equipment helps ensure the quality and performance of your products, and, therefore, the satisfaction of your customers.
This “measurement confidence” can be quantified by the performance specifications of your equipment, and calibration is the process that certifies your equipment is performing accurately and within specified tolerances. Therefore, it is paramount to find a calibration service provider that will best meet your needs.
A majority of today’s instruments come with variety of connectivity technologies. Knowing and deciding the most appropriate technology early as part of your test strategy can help you make the most out of your test automation. Here we list and compare various connectivity technologies for stand-alone instruments (non-modular). While the comparison is not exhaustive, it serves as a good starting point for any business beginning to investigate the available technologies.
The information in a test equipment datasheet can be an important tool for understanding a unit’s features and whether it will fit your lab’s needs. But do these datasheets promise too much? We regularly get questions from engineers about units that do not perform as they would have expected based on the information in the datasheet. To address this mismatch between what’s outlined in the datasheet and the unit’s actual performance, we need to understand that not everything that is written in the datasheet is guaranteed.
Last week, we began analyzing the economics of test automation by discussing its cost, from development to deployment to operation. But looking solely at cost can make the decision to adopt test automation both intimidating and lopsided, so we should also consider the benefits that we can reap from automation.
This week, we look at 5 benefits that test automation can bring to your organization: higher workforce productivity, yield improvement, better test throughput, high scalability, and quality improvement.
Perhaps your organization has been manually testing products over the years and is now mulling over the possibility of automating these tests. The decision to switch from manual to automated testing can often be a tug-of-war between management and engineering. From a management standpoint, costs and ROI are of considerable concern since it involves a certain amount of investment to make the switch. From an engineering perspective, automated testing should lead to better yield, higher productivity and improved quality, which would ultimately translate into cost savings.
