ByteSnap Design has expanded its capabilities by launching an early EMC testing service and investing in a testing chamber.

Dunstan Power, ByteSnap's director, said: "The chamber is great news for clients as, through our EMC testing services, they'll get an even more cost effective production service. Our clients will gain a clearer picture of how well the product is working, prior to going through the formal approval process. Our new chamber will identify any issues early and contribute to minimising the cost of fixes and avoiding repeat testing."

The EMC chamber, pictured during delivery, will be also used to make comparative signal strength measurements for low power radios to check performance over time, or the effect of modifications. While this service is not a replacement for R&TTE testing, it will reduce project timescales and increase efficiency, the company claims.

EMC test failure rates can be high, especially in complex projects using current high frequency and high speed components. Early testing minimises the risks of failing the formal EMC test.

Keysight Technologies has introduced a power analyser that combines power measurement with a touch driven oscilloscope. The IntegraVision power analyser is said to make it easy for R&D engineers to access dynamic views of current, voltage and power so they can see, measure and prove the performance of their designs.

According to Keysight, while some current power analysers offer adequate measurement accuracy, they are cumbersome to use and lack the ability to characterise power consumption under dynamic conditions. Ken Christensen, Keysight product manager, said: "Engineers typically use two instruments to measure power: a power analyser, for accuracy; and an oscilloscope, which adds a dynamic capability. IntegraVision is aimed at those engineers who need to measure AC/DC power consumption and conversion efficiency while accessing common parameters such as frequency and phase."

IntegraVision allows common AC power parameters, such as frequency, phase and harmonics, to be measured with 0.05% basic accuracy and 16bit resolution. It can capture 5Msample/s and has a 2MHz bandwidth.

The user interface is based on technology from Keysight's InfiniiVision 6000 X-Series oscilloscope, including its 12.1in capacitive touchscreen.

The device is available in a two channel, single phase version, or in a four channel, three phase format. The two channel variant will ship in May 2015, whilst the other instruments ships towards the end of 2015.
