News and technical information about test & measurement equipment and strategies from the point of view of the R&D or design and development engineer. Topics include T&M hardware such as oscilloscopes and signal generators/analyzers, as well as software and test methodologies.
LXI and PXI instruments and related software provide the synchronization necessary for making complex measurements, and they enable test automation in the lab.
The Avnet Electronics Marketing operating group of Avnet Inc has announced the Xilinx Spartan-6 LX16 FPGA evaluation kit and Spartan-6 LX150T FPGA development kit. Both kits support the new FMC (FPGA-mezzanine-card)-expansion standard, which enables the addition of add-on modules and customization when working with FPGAs.
Tektronix has expanded the RSA6000 series of spectrum analyzers to include the RSA6120A, which extends top bandwidth from 14 to 20 GHz, making the instrument suitable for applications operating at 12 to 18 GHz.
At the Design Automation Conference, which took place in San Francisco in July, Synopsys Inc highlighted the latest release of its Galaxy Implementation Platform, which, the company claims, delivers two-times-faster design implementation and sign-off throughput by leveraging multicore performance and MCMM (multicorner/multimode) technologies.
The ADS channel simulator's new statistical mode supports the design and verification of high-speed, chip-to-chip data links found in most consumer and enterprise digital products produced today.
Manufacturers are offering SOI and MEMS alternatives to PIN-diode, GaAs, and electromechanical switches for a variety of RF applications, but you need to understand RF-switch specs before you commit to a new technology.
From RF/microwave-circuit-design tools to electromagnetic simulation, EDA companies work with instrument vendors to get high-performance, high-quality products to market.
Many test engineers sidestep the built-in capabilities in today's RF-test equipment and devise their own algorithms, applications, and automated tests.
The lowly scraper is the best tool for the job. Given the right curvature, you can scrape a path just wide enough to reveal a trace under test without exposing other nearby features.
Whatever the interface standard, real external instruments and systems that gather test data and external software that performs yield-learning and other analysis tasks must supplant embedded instruments.
Because real-time oscilloscopes are workhorses in any laboratory, it’s important to know how to get the most out of them. Jitter measurements are particularly sensitive to their environment.

Comments (0) EDN technical editor Paul Rako is working on a January cover story on what he calls disintegration–not stuff falling apart, but rather the idea that it’s not always a good idea to cram more and more into a single IC.As Paul puts it, “There has been a historical tradition in electronics to integrate as many functions as possible into one chip,” but his article looks at c ...... « Read and comment »

Comments (0) Santa Clause may be coming to town with a bag packed with consumer electronics. The Wall Street Journal reports that “early holiday spending suggests a strong season for TVs, videogames.” The article says that US shoppers spent 6.1% more on electronics in the first half of November than they did in the first half of November 2008, according to MasterCard SpendingPulse data, which tak ...... « Read and comment »

Comments (0) It sees you when you’re sleeping,
It knows when you’re awake,
It knows if you’ve been bad or good,
So be good for goodness sake!
I’m not referring to Santa Claus coming to town, but rather the smart grid, which Siliconvalley.com says might be just a little too smart. That’s in reference to a new report from the Ontario Information and Privacy Commissioner and the ...... « Read and comment »
