While Australia's railways continue to be riddled by different, often incompatible communications systems, the efficiency and continued development of the network are at risk. Antoine Rouot of Nortel discusses a new digital radiocommunications system.
PacSat Antennas has launched a range of 5.8 GHz solid parabolic dishes. Solid dishes have a number of advantages over parabolic grids - particularly in high traffic: better front-to-back ratio (greater immunity to interference); more uniform and narrower beam-width; more robust than panel-type equivalent.
For most electronic systems, monitoring system voltages with a power-on reset (POR) ensures proper initialisation at power-up
Gage Applied Technologies has released a digitiser for the PCI platform. Operating at 200 MS/s (5 ns sampling intervals) with a resolution of 14 bits, the CompuScope 14200 is a general-purpose digitiser aimed at satisfying precision signal capture requirements in various fields of scientific and commercial research, development, as well as manufacturing test applications.
