Signal integrity tests often display results in an "eye" diagram that relates signal timing to signal levels. When testing a communication channel, for example, test equipment compares an eye diagram of acquired data with an eye template defined by standards organizations. When you perform tests on digital devices, similar eye diagrams can provide information about signal integrity.
Stand-alone instruments and instrument cards can adjust voltages and timing to perform signal-integrity measurements in digital systems. But the situation gets complex when tests involve hundreds of real-world digital signals.
You might not think of a logic analyzer as a signal-integrity tester. The state/timing modules for the 16700 family of logic analyzers from Agilent Technologies, however, provide built-in capability to construct such eye diagrams. The modules vary signal thresholds (windows) to monitor signal levels at specific times. The logic analyzer simultaneously measures hundreds of signals to build up signal-integrity information for each channel.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
