Abstract
A method for analyzing a measured signal is described wherein at least a first segment and a second segment of said measured signal are acquired by a measurement device. At least said first segment and said second segment are stored in an acquisition memory of said measurement device. A search criterion is applied on at least said first segment and said second segment. At least a first timing event corresponding to said search criterion is stored into a memory, said first timing event being found in at least one of said segments. Further, an oscilloscope is described.
Claims16
A method for analyzing a measured signal, the method comprising the following steps:
- a) acquiring at least a first segment of said measured signal and a second segment of said measured signal by an oscilloscope,
- b) storing at least said first segment and said second segment in an acquisition memory of said oscilloscope,
- c) applying a search criterion on at least said first segment and said second segment by a processor unit of said oscilloscope, and
- d) storing at least a first timing event corresponding to said search criterion into a memory, said first timing event being found in at least one of said segments;
- wherein a segment player plays all segments in a successive manner, said playing being automatically halted if said segment to be displayed comprises said first timing event, and
- wherein said search criterion is associated with at least one of a pulse width, a certain signal level, a glitch search, a runt pulse, or a search criterion selected by a user.
An oscilloscope for analyzing a measured signal, said oscilloscope comprising:
- a signal input for receiving a signal to be measured;
- an acquisition circuit with an acquisition memory, said acquisition circuit being configured to acquire at least a first segment of said measured signal and a second segment of said measured signal such that at least said first segment and said second segment are stored in said acquisition memory;
- a processor unit configured to access said acquisition memory and to apply a search criterion on said data acquired, said processor unit being further configured to store at least a first timing event corresponding to said search criterion applied into a memory of said oscilloscope, and
- a segment player connected to said acquisition circuit, said segment player being configured to access said acquisition memory and to play all segments acquired in a successive manner, said segment player being configured to automatically halt said playing if said segment to be displayed comprises said first timing event,
- wherein said search criterion is associated with at least one of a pulse width, a certain signal level, a glitch search, a runt pulse, or a search criterion selected by a user.
A method for analyzing a measured signal, the method comprising:
- acquiring at least a first segment of said measured signal and a second segment of said measured signal by an oscilloscope;
- storing at least said first segment and said second segment in an acquisition memory of said oscilloscope;
- applying a search criterion on at least said first segment and said second segment by a processor unit of said oscilloscope;
- and
- storing at least a first timing event corresponding to said search criterion into a memory of the oscilloscope, said first timing event being found in at least one of said segments,
- wherein only one segment of said segments is displayed at a time such that the search criterion is applied on at least one segment that is not currently displayed on a display of the oscilloscope,
- wherein said first timing event is stored in said memory irrespective of the segment currently displayed,
- wherein a segment player plays all segments in a successive manner, said playing being automatically halted if said segment to be displayed comprises said first timing event, and
- wherein said search criterion is associated with at least one of a pulse width or a glitch search.
