6. SEPARATION OF SIGNAL AND POWER
wiring in separate
conduits is the traditional precaution, however, other measures must
be taken to minimize the effects of electromagnetic interference
(EMI) and radio frequency interference (RFI) on the operation of the
instrument. Otherwise, if high level, short duration, noise spikes are
permitted to enter the digital equipment, the noise can be transferred
into the systems logic networks and can be misinterpreted as signal
data, resulting in erroneous system operation and other unpredict-
able responses. Potential noise sources: Relay coils, solenoids, AC
power wires, current carrying cables, or radio frequency transmis-
sions.
