1. sequence trigger method that is used for digital oscilloscope, the trigger process of digital oscilloscope comprises searched events and trigger event, have switch in described searched events and the trigger event respectively, described trigger event is each trigger condition of digital oscilloscope, it is characterized in that comprising following step:

  • (1) in the searched events stage, judge whether the switch of searched events is opened, just can enter the trigger event stage if open then wait until when searched events satisfies, if close then directly enter the trigger event stage;

    (2) in the trigger event stage, detect the executive condition of each trigger event in order one by one, till the trigger event that detects last switch opens, this moment, the number of times of trigger event counter added 1;

    When detecting the trigger event of last switch opens, judge whether the value of trigger event counter equates with the cycle index that sets in advance, if equal then produce a trigger pip and return step (1), otherwise continuation execution in step (2).
