Power versus Time Measurement Description

Trigger Source

Triggering choices available for the PvT measurement are RF rise, protocol, immediate, and auto. In most
cases, auto triggering provides the optimum measurement triggering condition for the PvT measurement.
When auto triggering is selected, the test set chooses a trigger source based on the optimum trigger source
available. For example, PvT measurements will automatically be triggered by a protocol trigger if a call is
connected or call processing events provide the protocol trigger source.
In situations where no protocol trigger is available, the test set will choose RF rise triggering for the PvT
measurement. An example of this situation might be when the test set is in test mode operating mode.
