<p>The operational state transitions and events of an RF transmitter having a plurality of operational states are monitored and recorded. A plurality of ports are provided that each receive an indication of an occurrence of an event that can cause a transition from one state to another of the plurality of states. A transition status memory stores transition status data representing the status of each associated state. A micro-controller is programmed so that it determines, for each state, from the indications whether a state transition has occurred and, if so, it causes an appropriate change in the associated transition state data stored in the memory.</p> |
