Test & Measurement

Test and measurement equipment underpins the product design process, enabling engineers to verify their design is working in the way they want. If not, these essential devices help them to find out where the problems lie.

In this section, New Electronics keeps design engineers up to date with the Test and Measurement market, bringing a range of information about the products and their application.

Automating oscilloscopes: how to save time and make better measurements

Oscilloscope measurement automation has become imperative for timely and accurate debug and validation. In many cases, the number and complexity of tests demanded by a technology standard or application prohibit any attempt at manual measurements. For example, the DisplayPort compliance tests require 312 different test conditions at eight waveform locations – 2496 unique measurements! An automated oscilloscope can complete these measurements in a few hours, where manual measurement will require multiple man days.

Test equipment helps embedded system designers debug their rf connectivity

It wasn't too long ago that wireless communication was only available using devices designed solely for that purpose; walkie-talkies and the like. But over the last few years, wireless communication has found its way into all manner of products. Today, providing the ability for a product to communicate via Wi-Fi, gsm or other rf technologies is almost expected. What might once have been pretty much a digital design is now more complex – and the tools needed to design and test these products have had to adapt to new demands.

Smart metering needs smarter test

In the next few years, homes and business across the UK will receive a Smart Meter: a device that will provide detailed information on how energy is being used, helping to reduce consumption, bills and their carbon footprint. The rollout of smart meters is also a major step towards realising the Smart Grid and utility companies are racing to update systems and infrastructure to deliver this massive change to electricity, water and gas metering and billing.

A holistic approach: Equipment rental brings flexibility to design engineers

While a lot of companies invest in equipment which meets their day to day test and measurement needs, every now and then they need something more sophisticated and more expensive. In austere financial times, management has to keep expenditure under control without compromising on product quality, so the balance is shifting in how companies acquire equipment. Equipment rental companies, such as Microlease and Livingston, offer full solutions that reflect a holistic approach to this dilemma.

Testing efficiently an increasing challenge for design engineers

When thinking about product testing, most people focus on the area of most interest to them. A software engineer might want to test firmware before a new release, whilst a compliance engineer might want to examine the regulatory hurdles to a product release in a target country. It could be argued that it is important to have an overall picture of the entire gamut of test areas as they become more interdependent.

Modular instrumentation set to meet new test challenges

The world of test and measurement is changing; slowly for some, but at a rapid clip for other users. This change is seeing users moving away from traditional instrumentation in favour of modular devices. It is, in the opinion of some companies, the end of the so called 'rack and stack' era – and it's all being driven by the benefits derived from Moore's Law.

How in the loop testing aids embedded system validation

Embedded systems software can provide competitive advantage. For a vehicle, software can make a comfortable ride even more appealing; it can also reduce cabin noise or fuel consumption. Some of this functionality could, potentially, be implemented in hardware, but that would increase manufacturing cost and product price. Software also enables reuse and can be updated more frequently to satisfy user needs.
