Abstract
A time interval analyzer for measuring time intervals between events in an input signal includes a trigger circuit that receives the input signal and that outputs a time trigger signal at a first triggering level upon occurrence of a first input signal event. A time counter receives a time base signal and increments a time count at each period of the time base signal. The time count is calibrated to a predetermined reference time. A processor circuit is in communication with the trigger circuit and the time counter so;that the processor circuit receives the time trigger signal and reads the time count from the time counter. The processor circuit is configured to read the time count upon receiving the time trigger signal at the first triggering level so that the time count read by the processor circuit indicates the time at which the first input signal event occurred with respect to the predetermined reference time.
