You wrote: <Can somebody tell me what does TEMPEST stand for ?> I don't think that the letters stand for anything, rather it is a (British?) set of performance specs, standards, requirements essentially aimed at maintaing confidential communications. E.g. a Tempest monitor will not bleed video or z modulation signals that may be picked up by a sensitive receiver nearby. I've seen a demosnstration at an exhibition where the exhibitor of an 'Intrusive Monitor System' was able to dut up a screen display of all the screens around him at will, just by homing in on their timebases and video signals with a highly directional antenna. TEMPEST, seeks to eliminate this leak of 'intellligence'. It's not only monitors, but data comms, RF, printers, anthing which could radiate, or conduct, data to an interested and well equipped third party. At least I think that's what it is. :-) Chris Dupres Surrey UK. --------- This message is coming from the emc-pstc discussion list.
