Simplifying frequency converter testing
Traditionally, VNAs have been used to characterise the magnitude and phase performance of a mixer or frequency converter. This article features a test method that fully characterises mixers and frequency converters without reference and calibration mixers. [ + ]
Electronex exhibition is the biggest yet
The third year of Electronex, being held at the Australian Technology Park in September, is now 50% bigger than the first exhibition. [ + ]
Keeping track of data centre functions
Many IT administrators are unaware of the current use levels of their server racks and IT infrastructure. This article explains how RFID technology can improve the security and efficiency of data centres. [ + ]
Enclosures are the first line of defence
This article explains the international standard for enclosures (EN 60529) and defines the protection rating they receive. [ + ]
Melanin links biology and electronic sensors
There is now insight into the electrical properties of melanin and its biologically compatible ‘bioelectronic’ features. [ + ]
Hybrid energy for network power
Telecom providers across the globe are searching for ways to more efficiently power and operate their networks. [ + ]
Monitoring and analysing lightning strikes
A lightning monitoring system detects and analyses lightning surge currents, providing a way to evaluate the actual system load. [ + ]
Controlling the make-up of nanowires
Nanowires are a hot research topic, with a variety of potential applications including light-emitting diodes and sensors. [ + ]
When components need to keep their cool
This article looks at some of the various methods of heating and cooling a DUT. [ + ]
Antenna simplifies LTE indoor coverage
Distributed antenna systems (DASs) are now being deployed to provide indoor coverage. More than 80% of all mobile data calls are initiated inside a building, whether an office, airport, railway station, stadium or home and therefore it is absolutely critical for service providers to provide both good coverage and quality of service inside buildings.

When a memory recorder replaces an oscilloscope
Memory recorders are specfically designed for industrial situations and oscilloscopes are not. [ + ]
Tandem encoders give two axes and one power input
‘Tandem Encoder’ is a new term but one which is increasingly being used by mechanical and electrical designers. Mark Howard of Zettlex* explains what a tandem encoder is, how it works, its technical features and where it is best used. [ + ]
Assembly errors quickly identified
Researchers at the Fraunhofer Institute for Factory Operation and Automation IFF have come up with a testing technology to help reduce assembly errors. [ + ]
Radio waves trigger insulin production
Radio waves have been used to remotely switch on engineered insulin-producing genes in mice. [ + ]
Shelve the idea of a simple rack
Rittal looks in depth at the requirements of a modern rack and the duties it is expected to perform in a data centre. [ + ]
