World's First RF / EMC ‘Camera System’

The SPECTRAN RF VIEW from German-based Aaronia is a unique RF measurement system consisting of an array of complex measurement setups at each "RF pixel" of the RF ‘camera’. Each unit consists of a Spectrum Analyzer from Aaronia’s SPECTRAN RSA series with a connected isotropic broadband antenna, each of which is network-connected to a central server. The antennas are arranged in an equidistant X / Y matrix grid. The measurement data (amplitude and/or frequency) are visualized on a PC somewhat like a ‘chessboard-display’. Each field of the ‘chessboard’ represents a measurement data locationAnRF camera’ with 8x8 points (64 pixels resolution) thus requires 64 measurement units.  While this resolution may seem rather small, it allows amazingly detailed measurements of antenna spread characteristics or the graphical classification of radiated emissions during an EMC test or experimental adjustments. The SPECTRAN RF VIEW saves considerable measurement time and allows for very detailed information on the spreading patterns of emissions. The system can be extended to any size in order to reach much higher resolutions and has already been successfully used for research programs and product evaluation for a leading European telecommunications provider.  -Despite the considerable hardware setup, the system price is quite reasonable, bearing in mind the valuable experimental time that is saved. A 32-pixel system with 6GHz range is currently available, with versions up to 20GHz bandwidth also available by request at higher cost.   For detailed specifications, free technical assistance, or additional information, please contact Tech Support at Saelig.
