How to do Echo Sounder Test?
Antenna Height:The distance from the center of the GNSS to the surface of the water does not need to be entered here, just set it to 0.
Transducer Draft:The distance from the bottom of the transducer to the water surface
Power:0-12, the transmitter power of the echo sounder, increase appropriately when the water is deep.
Gain:0-30. In actual work, due to the weakness of the echo signal, the signal must be amplified before the echo sounder is processed, that is, the amplitude of the signal is increased by the amplifier circuit, and the adjustment of the gain is to adjust the multiple of the amplification. This
function not only amplifies the echo signal, but also the clutter is also amplified, so it is necessary to set an appropriate value according to the echo image to ensure effective echo quality.
TVG Gain:1-8: When sound waves propagate in water, the sound intensity decays exponentially. In order to keep the signal amplitude stable, TVG will control the receiving amplifier to increase the amplification factor according to the opposite law, which is called time gain control.
Pulse width:1-8, used to control the width of the transmit pulse.
Threshold:1-9. If your measurement area or environment has a lot of interference, you can increase the detection threshold setting. If the detection threshold increases, the interference signal can be filtered out. However, the detection threshold should not be too large. If it is too
large, the weaker echo signals may also be taken into consideration.
The difference in the threshold will affect the sounding accuracy to a certain extent, so the appropriate selection of the
appropriate signal threshold is useful for suppressing interference and stabilizing Tracking is good
