4.9.3 Trigger Configuration
Figure 4-56
Hardware part for the Trigger Configuration
The Trigger Configuration allows the operator to control the pulse length
and delay characteristics.
When the trigger input is enabled (Active) the ping will occur upon receipt
of the input
trigger pulse. If the trigger pulse rate exceeds the sonar’s
actual maximum ping rate for that range setting, some trigger input pulses
may be dropped.
When the trigger input is disabled the sonar will return to ping at the rate
dictated by the settings in the main and advanced Control pane.
By default the trigger output is enable (Active). This means that a pulse
will be generated in conjunction with the sonar ping.
Figure 4-57
Example of trigger output with Delay = 0 and Pulse length = 1
The Delay allows the operator to specify how many milliseconds after the
sonar ping the output pulse will be sent.
The Pulse length allows the operator to change the pulse length of the
transmitted output signal.
4.9.4 Ping Settings
Figure 4-58
Hardware part for the Ping Settings
The Ping Settings will give the sweep frequency for the pulse type FM.
Settings can only be changed when the pulse type FM is selected in the
advanced pane.
