Description
Technical field
The present invention relates to digital oscilloscope technical field more particularly to digital oscilloscope method for displaying waveform and device.
Background technology
Current digital oscilloscope product is equipped with color display screen, for showing a series of of capture signal waveform
Sampled point.One of the advantages of digital oscilloscope, is to the signal waveform sampled point of storage capture, facilitates user to signal wave
Shape carries out more careful observation and measurement.
Current digital oscilloscope is all configured with sufficiently long storage depth, and more wave can be obtained by once acquiring
Shape sampled point, user can be further to these waveform sampling point analysis, measurements.It can also be incited somebody to action by oscillograph upper computer software

1st, a frame Wave data is once read, oscillograph is generally operational in single-trigger mode, is completed after oscillograph triggering
Primary acquisition just stops, and then once can all read the Wave data in oscillograph memory, at this time full memory data
An only corresponding frame waveform, after full memory data are read, can do further waveform analysis or by remote in oscillograph
Internal storage data is reached PC and does advanced analysis by journey order, such as the spectrum signature of signal is calculated.
2nd, recording and playback mode, oscillograph are carried out continuously multiple triggering, acquire a frame Wave data, continuous acquisition every time
Repeatedly, all Wave data frames are all preserved in memory, waveform playback data or remote command then can be passed through frame by frame
Wave data frame in memory is reached into PC and does advanced analysis.Such as a kind of display of unusual waveforms is provided in the prior art
Method, this method can carry out abnormality detection the waveform of recording, will by the Wave data of recording compared with a reference waveform data
Unusual waveforms data are shown in the window, and can show the relationship between unusual waveforms data and front and rear Wave data.
However, both the above mode can only all be analyzed for complete frame Wave data, first way can be
Frequency domain analyzes waveform, but frequency domain conversion is to be directed to whole frame data, and waveform is not analyzed in time domain.Second
Kind mode can analyze multiframe unusual waveforms and unusual waveforms frame and the relationship of front and rear waveform frame, but the detection of abnormal frame is
For whole frame data, time correlation analysis can not be carried out to the data in frame, in addition anomaly analysis is for time domain, not in frequency
Domain is analyzed by waveform.In short, both the above mode all cannot provide time domain, frequency-domain combined analysis to Wave data, it is impossible to
Provide temporal correlation of the digital oscilloscope signal on time domain, frequency domain.
