What is EMC?
Electromagnetic compatibility describes a level of performance
of a device within its electromagnetic environment. This
environment consists of the device itself and its surroundings
including other equipment, power sources and persons with
which the device must interface. Inadequate compatibility results
when a susceptible device fails to perform as intended due
interference from its environment or when the device produces
unacceptable levels of emission to its environment. This
interference is often referred to as radio–frequency or
electromagnetic interference (RFI/EMI) and can be radiated
through space or conducted over interconnecting power of
signal cables. In addition to electromagnetic energy, EMC also
includes possible effects from electrical fields, magnetic fields,
electrostatic discharge and disturbances in the electrical power
supply.
CE Compliance
LOGIQ e conforms to all applicable conducted and radiated
emission limits and to immunity from electrostatic discharge,
radiated and conducted RF fields, magnetic fields and power
line transient requirements.
For applicable standards, refer to the Safety Chapter of the
Ultrasound system’s User’s Manual.
NOTE: For CE Compliance, it is critical that all covers, screws,
shielding, gaskets, mesh, clamps, are in good condition,
installed tightly without skew or stress. Proper installation
following all comments noted in this service manual is required
in order to achieve full EMC performance.
