2014 in Test and Measurement: Sensing, troubleshooting and HMI transformation
From current sensing to troubleshooting and HMI topics: Measuring is one of the most fundamental disciplines of engineering. Almost every engineer is involved in some king of measurement tasks. And much like other aspects of the engineer's work, testing and measuring is driven by constant changes. The list of the most popular articles in EE Times Europe's Test and Measurement section reflects this challenges - here are the articles that attracted the most interest from our readers.

Troubleshooting on the move

Today's engineers and technicians face increasingly complex and critical troubleshooting tasks. Designs that work fine in the lab can sometimes fail in the field, causing customer dissatisfaction, lost production, expensive repair bills and, sometimes, safety concerns. With the customer impatient to get their system fixed as rapidly as possible there is huge pressure to troubleshoot and fix problems quickly and accurately.

Sensing elements for current measurements - Part 1

Ryan Roderick of Intersil explains how to choose a sense resistor and discusses the inaccuracies associated with the sensing element and the extraneous parameters that compromises the overall measurement.

Considerations When Specifying a DC Power Supply

Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. DC supplies provide power to the device under test as well as test stimulus. In some cases, the supply used to provide power to the DUT also provides a test stimulus by simulating the operating environment. For example, while most automotive electronics run at a nominal 12 VDC, the maximum input voltage may be as high as 27 VDC. Because this is so, some automotive standards require margin testing up to 27 VDC on a 12 VDC device. Necessities such as these determine power supply requirements.

Slideshow: Top 10 sensor trends to follow

Here's a look at 10 trends in 10 sensor applications emerging from the recent International Consumer Electronics Show (CES) and over the past year.

Impedances on the test bench

Almost all designers and producers of digital high-speed systems are about to face the challenge of having to consider high-frequency design aspects. Specifically, this is about optimal data transfer being only possible on transmission paths with correct impedance ratios. Learn more about adequate measuring technology here.
