About synchronization
Whenever more than one hydroacoustic system are installed on a vessel, interference may
occur. With only two systems, interference can be avoided if one of the hydroacoustic
systems can control the transmissions of the other system. If multiple systems are used, they
can be connected to a common synchronisation system that controls all the transmissions.
In physics, interference is the phenomenon in which two waves superpose each other
to form a resultant wave of greater or lower amplitude. Interference usually refers to
the interaction of waves that are correlated or coherent with each other, either because
they come from the same source or because they have the same or nearly the same
frequency. Interference effects can be observed with all types of waves, for example,
light, radio, acoustic, surface water waves or matter waves.

The Simrad ES80 may be set up to be synchronized with other hydroacoustic instruments.
Synchronization is necessary to prevent several hydroacoustic systems from transmitting
simultaneously. Individual transmission is often a necessity to prevent interference.
