This feature provides a hardware trigger output from the rear panel of the test set to control external instruments and devices. It is an extension of the trigger provided in earlier applications. Frame triggers and protocol message-based triggers are available, based on various layers of the protocol stack.
The original trigger could be set to trigger on every TDMA frame with user-settable timeslot and symbol positions. PETO offers additionally:
Any combination of frame and protocol triggers can be enabled at the same time. Triggers fire in the order in which they occur, but all triggers are output on the same Trig Out port. It is not possible to discern which trigger has fired based only on the output signal.
If triggers occur at the same time, only one signal will appear on the port. Choose triggers carefully to provide the most meaningful results.
