8 FINAL TESTS AND MEASUREMENTS
8.1 General
In order to verify that the sonar works properly, the following
measurements and tests must be carried out:
- Source Level (SL) measurements
- Receiving voltage response (VR)
- Noise/speed curve
To make these tests and measurements, an oscilloscope, a signal
generator and a test hydrophone must be available.
8.2 Source level (SL) measurements
In order to get the TX ENABLE pulse on the auxiliary connector
on the Sonar Control Unit, two wires have to be moved on the
connection terminal E201 in the Transceiver Unit.
j Disconnect the wires in cable pair no. 6 (E201--31 and
E201--33).
j Connect the red wire to E201--49 and the blue wire to
E201--46.
Now the TX ENABLE pulse is available in the auxiliary connector
as shown in figure 14.
