Transmitter Unit

Transmitter Unit description

The EM 712 Transmitter Unit has all transmit electronics, like control processors, power
amplifiers, power supply, capacitor battery and Ethernet interface.
The Transmitter Unit is a wall-mounted steel cabinet
with integrated shock and vibration absorbers, designed
for bulkhead mounting. One 19 inch sub-rack is
contained in the cabinet. The number of circuit boards
in the sub-rack will depend on the chosen transducer
configuration.
Twisted pair Ethernet is used for data communication
with the Processing Unit.
The Transmitter Unit is normally located in a "sonar
room" close to the transducer arrays.
For a 0.25° transducer array, two Transmitter Units are used.
