Patent ID: 8161497

Claim:
A method, for use in an oscilloscope, of capturing for display all data associated with all trigger events within an input signal under test, comprising steps of: detecting, in trigger detection circuitry, the trigger events within the input signal to generate a trigger signal; drawing, on a display screen of said oscilloscope, a first display frame for the input signal based upon a first trigger event within the trigger signal; and drawing, on said display screen of said oscilloscope, a second display frame for the input signal based upon a subsequent trigger event within the trigger signal after the first trigger event, the second display frame having minimal overlap with the first display frame when the subsequent trigger event occurs within a designated interval after the first trigger event and the data associated with the trigger events within the first display frame are captured for display; said drawing of said first and second display frames on said display screen being controlled by a controller, and including said display of all data associated with all trigger events within said input signal under test; wherein the designated interval comprises a sum of a desired pre-trigger time interval and a desired post-trigger time interval, the designated interval starting when the first trigger event occurs.
