The end of American motors Blog 2/24/2011 28 comments The last domestic motor manufacturer is now in foreign hands. On top of it, imported motors are not meeting energy-efficiency requirements here in the land where such design considerations first emerged. Just what’s going on?
Hold on to your instrument The Engineering Life - Around the Web 2/24/2011 Post a comment Have you ever returned from vacation (or a weekend, or even just overnight) to find that you test bench had been raided?
Does EMC stand for exasperating, magic, or confusing?¬—Part 2 Design How-To 2/21/2011 2 comments While it is merely a nuisance to experience radio interference, it is definitely a serious matter if an ABS, stability control, or airbag suffers a malfunction because a vehicle passes a TV tower too closely. Thus, mastering EMC is a basic requirement for automotive electronics designers. Part two of this article outlines methods to suppress high-frequency resonance.
Let the RAT race begin… RF & Microwave Designline Blog 2/14/2011 Post a comment So are you ready for the biggest mobile industry wireless event on the old continent? The buzz at least in the test and measurement space is who are the first ones on the market supporting LTE-Advanced, the Release 10 of the 3GPP standard, the evolution of the Long-Term Evolution, 4G and beyond.
Air of promise filled DesignCon RF & Microwave Designline Blog 2/13/2011 3 comments With strong booth traffic, well-attended presentations and an overall positive feeling, it was proof that trade shows and exhibitions still have a prominent place in our industry.
Beating signal degradation in wireless networks Design How-To 2/13/2011 4 comments For wireless operators, using passive intermodulation distortion (PIM) equipment correctly requires greater care than standard voltage standing wave ratio (VSWR) site sweeps or distance-to-fault transmission line testing.
'You asked for it, you got it, Toyota' Automotive DesignLine Blog 2/9/2011 19 comments The U.S. government has vindicated Toyota's electronic control technology in the spate of sudden acceleration incidents, but what happens to the automaker's reputation?
Who Needs Pulsed I-V Testing? Test & Measurement Designline Blogs 2/9/2011 Post a comment Recently, there has been a surge in the number of applications that require ultra-fast I-V measurements, which involve generating pulsed waveforms, then measuring the resulting signals before the DUT has an opportunity to relax.
Measuring satellite end-to-end group delay using a microwave system analyzer Design How-To 2/9/2011 Post a comment The relative group delay measurement across the bandwidth of satellite transponder channels is important, in order to determine the amount of distortion or signal degradation that could take place due to increased delay changes at the band edges of these channels. The delay must be measured in order to apply accurate compensation and thus avoid possible data corruption.
Don't be an easy catch: test your products before deployment Design How-To 2/2/2011 2 comments Bugs are more than a nuisance; they are a hole in your security through which crackers can access your systems. The number one security threat is not a malicious attacker, but poorly managed development processes. Technologies are increasingly complex, and at the same time release cycles are not only faster, but also more complicated, involving outsourcing. The later testing is carried out, the more difficult it is find the problem. And, the later you test, the more expensive and less thorough t
Optical power measurement and resolution Design How-To 2/2/2011 Post a comment The modern optical spectrum analyser (ASA is a powerful tool for carrying out a variety of measurements, but as many users do not appreciate some of its potential applications. In this article, the relationship between power measurements and resolution os discussed, with the aim of showing users how understanding the technical principles of the OSA will allow them to get the most out of the instrument.
Measuring the resistivity of bulk materials Design How-To 2/2/2011 Post a comment Accurate resistivity measurements are critical when characterizing materials, but they are not always easy to make and different material types require different instrumentation and techniques. This article addresses best practices for making resistivity measurements.
It’s a mad, mad, electronics test world News & Analysis 2/1/2011 4 comments The proliferation of wireless devices and the demand for low-cost and high-performance products are all part of global wireless traffic that is expected to grow to 600 Terabytes per month mostly consisting of audio and video streams by 2014, according to market reports.
The Other Tesla David Blaza5 comments I find myself going to Kickstarter and Indiegogo on a regular basis these days because they have become real innovation marketplaces. As far as I'm concerned, this is where a lot of cool ...
