Periodic Triggering
Periodic triggering provides a means of capturing a defined amount of IQ data on a
periodic basis. Periodic triggering is typically used for statistical analysis of the captured
signal.
External Triggering
External triggering provides a means of synchronized triggering based on the receiving of
a trigger signal provided via the WSA5000's GPIO. The trigger “signal” could be a single
pulse or a sync-word. See

Caution:
Contact ThinkRF's Support for details on how to use the GPIO port prior to
connecting anything to the port.

Capture Controller
The Capture Controller provides a means of defining and performing simple traces and
complex sweeps. For example, it allows for:
•
the definition and execution of a complex sweep;
•
the interruption of that sweep;
•
the execution of a specific trace; and
•
the resumption of the previous sweep.
