ABSTRACT:
A pulse measurement circuit for measuring timing parameters includes main and delayed trigger generators and a timer for measuring the time between generation of the two trigger signals. The circuit further includes an adjustable delay circuit that senses the main trigger signal and in response enables the delayed trigger generator for triggering after a selectable delay. To measure a timing parameter of a pulse, both trigger generators are first caused to trigger on the first parameter boundary and the time between generation of the two trigger signals is measured. The delayed trigger generator is then caused to trigger on the second parameter boundary while the main trigger generator again triggers on the first parameter boundary. The time difference between generation of the two trigger signals is again measured. The first time is subtracted from the second time to measure the time of the pulse parameter.
