Delayed sweep

Another feature of most good scopes is Delayed Sweep. Delayed Sweep, allows the user that could be you, if you behave and eat your vegetables to trigger on an event and observe the signal after some predetermined time interval. For example: if you wanted to observe one single scan lineout of 525in a television signal, you would trigger off of the beginning of each television field time 16.67 msec but holdoff displaying that particular scan line HD 63.5 usec until the correct amount of time has passed.
