What we saw:
In a
different direction from the somewhat ITE centric EMC presentations,
Chris Kendall accepted an invitation to speak to the RMCEMC on
Military EMC Design. Many new designs, especially those that employ
video systems, are utilizing digital high speed data buses including
DVI, Serdes, Fibre Channel, IEEE 1394 (Firewire), and Ethernet. In
some cases, all of the above are being incorporated into the same
system. Because they are located in the cockpit area of the aircraft,
these new designs are expected to meet MIL-STD-461E, RE102, external
limits. Additionally, if the aircraft can be deployed from aircraft
carriers (shipboard board environment), field strengths as high as
13,000 V/m (This is not a misprint!) may also be imposed. After a
brief summary of the interfaces - so desirable for our next generation
fighters -Chris showed how the high speed interfaces have
significant emissions and susceptibility issues using simulation
software. Then Chris got onto one of his self avowed favorites
subjects: Grounding and Referencing. Chris addressed the different
grounding theories and discussed the use of shielded cables with
different grounding techniques. Most remarkably, Chris showed how, in
one circumstance, the shielding properties of a coax was governed
mainly by the RESISTANCE of the cable. All in all a very
interesting insight to the complexities of Military design.
