YNCHRONIZATION
During external synchronization, the acoustic emission of GAPS antenna is set off by an
external appliance. This mode is chosen when GAPS is simultaneously operating with another
acoustic system. A signal is sent to GAPS by one of the two BNC links located at the front
and at the back of the BOX. The parameters associated with external synchronization are:
●
Inhibition
: this is the time after setting off during which GAPS cannot receive other
signals which could activate it at an untimely moment.
●
Activation
: this is the part of the signal where, on reception, the setting off takes place on
a
Rising Edge
of the signal.
●
Min. Duration
: this is the minimum length of time necessary for the setting off after
activation during which the signal must remain stable (high after a rising edge and low
after falling edge). Its values range from 50 µs to 1000 µs.
