Radio Transmitters
Radio transmitters
Radio transmitters couple the signals from sensors to the Eureka2R correlator.
One transmitter (red) is always used; the other transmitter (blue) may be
replaced by a direct cable connection (to the Eureka2R correlator), where
appropriate. The transmitter is a sealed unit powered by rechargeable
batteries.
To prepare the transmitter for use, connect the aerial (antenna) on the top of
the unit and then connect the sensor cable (hydrophone or accelerometer) to
the top port, under the rubber protective cover. Connecting the sensor turns
on the transmitter.
Radio transmitter LED indicators (top five indicators are level indicators; middle two indicators are status
indicators; object on bottom is the pushbutton)
WARNING: Do not leave the transmitter turned on (with a sensor
connected) without the antenna connected. This will cause the
transmitter to overheat.
The leak noise signal strength displays on the LED level indicators. If the top
(red) LED is illuminated, the signal is too strong and is saturating the radio.
(The red LED typically flashes intermittently at peak noise levels.) If the
