When synchronization starts, the
Trigger display
shows the current state of
triggering. It will indicate trigger by displaying a pulse on the blue trigger plot
(see figure
on page 31). The groups are separated by yellow group
markers (vertical line). Two lines are shown for each echo sounder: blue plot
displays the trigger pulses as they are generated; the colored plot (red/green/gray)
indicates the state and the events of the echo sounder. See the legend for description
in figure
on page 38. Note that the plot will always show a red pulse
whenever a transmit occurred (when not externally triggered, but free running).

The period of the trigger display can be set to 10, 30, or 60 seconds. The horizontal
axis shows the current time.

The
active period
in the echo sounder status indicates how long the ping cycle
of an echo sounder is (duration from trigger until echo sounder is ready again).
Multibeam systems will typically have the longest active period while single beam
system will have shortest active period (active period is the value to the right in
Figure
Echo sounder status for one particular echo sounder
on page 29 ).
