Duty cycle (or duty factor) is the ratio between pulse width and period time. The Analyzer determines this ratio by simultaneously making a pulse width measurement and a period measurement, and calculates the duty factor as:
This is not a back-to-back measurement, meaning that there is a dead-time of 50 ns between the samples. 2 signals can be measured in parallel. Up to 16 million samples total can be measured in a single measurement session.
