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?

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.

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

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
