An abnormal waveform capturing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 illustrates a method for anomalous waveform capture provided by an embodiment of the invention, which may be performed by an electronic device that may include: a server or a terminal device. In other words, the method may be performed by software or hardware installed on the electronic device, the method comprising the steps of:
s101: an eye diagram formed at a first time by the waveform to be detected is determined.
The eye pattern of the digital signal contains abundant information, reflects the overall characteristics of the digital signal and can well evaluate the quality of the digital signal. And taking the output of the transmission channel as the input of an oscilloscope to obtain an eye pattern corresponding to the signal before the violation time point.
In one implementation, step S101 in this embodiment includes: inputting the waveform to be detected before the first time into a target oscilloscope; adjusting the scanning period of the target oscilloscope to synchronize the horizontal scanning period of the target oscilloscope with the period of the received code element; and obtaining the eye pattern.
S102: a first measurement item corresponding to the eye diagram is determined.
There are many eye parameters associated with an eye pattern, such as eye height, eye width, eye amplitude, eye cross ratio, "1" level, "0" level, extinction ratio, Q factor, average power, rise time, fall time, etc.
In one implementation, the first measurement item includes: at least one of an amplitude measurement term, a time measurement term.
Wherein the amplitude measurement term includes: at least one of eye level, eye amplitude, eye cross percentage, eye height, eye signal to noise ratio, Quality (Q) factor, extinction ratio, vertical eye opening.
The time measurement items include: at least one of eye crossing time, eye delay, deterministic jitter, rise time, fall time, eye width, horizontal eye opening, peak-to-peak jitter, random jitter, root mean square jitter, total jitter.
S103: based on the eye diagram, a first measurement value corresponding to the first measurement item is determined.
On the basis of analyzing and calculating the eye pattern, a first measurement value corresponding to the first measurement item is determined.
In one implementation, the pixel points are counted on the picture formed by the eye pattern, and the corresponding measurement value is calculated according to the definition of the measurement item.
Take eye level, eye height, eye crossing time, rise time as examples. The eye level is defined as the magnitude of the "1" level and the "0" level in the eye diagram. The algorithm counts 20% of the area in the middle position of the eye pattern, makes a histogram in the vertical direction, and calculates the mean value of the two histograms, wherein the larger voltage amplitude is the level "1" and the smaller voltage amplitude is the level "0".
The eye height is defined as the difference between the voltage values of the eye diagram "1" level down by 3 standard deviations σ and "0" level up by 3 standard deviations σ. The algorithm calculates the standard deviation of the two histograms, and obtains the eye height according to the definition.
The crossing time is defined as the point in time of the eye crossing on the horizontal axis. The algorithm makes a histogram in a rectangular range of-Atotal BW + Atotal BW, and the eye crossing time is a time value corresponding to the mean value of the two histograms. where-Atotal is the value of the eye "0" level and Atotal is the value of the eye "1" level, BW is typically chosen to be 20%.
The rise time is defined as the time difference between 10% and 90% of the first rising edge of the eye pattern. The algorithm determines the voltage values of 10% and 90% of the eye pattern according to the eye '0' level and the eye '1' level, histograms are respectively made in the horizontal direction, and the time difference between the two histograms is calculated to obtain the eye pattern rising time.
And determining the corresponding first measurement value of the other first measurement items by using a statistical method according to the definition. For example, the eye signal-to-noise ratio is the difference between the "1" level and the "0" level divided by the sum of their corresponding standard deviations. The vertical eye opening is the vertical distance between two points on the vertical histogram at eye delay (EyeDelay), which is the time from the middle point to the far origin of the eye diagram. Where the eye signal-to-noise ratio, Q factor, vertical eye opening, deterministic jitter, horizontal eye opening, stochastic jitter, etc. are calculated using a dual dirac model, taking into account both stochastic and deterministic components.
S104: and outputting an abnormal waveform corresponding to a first time in the eye pattern when the first measured value does not meet a first preset condition.
When the first measured value in an eye pattern formed by the waveform to be detected at the first time does not meet the first preset condition, the waveform in the eye pattern corresponding to the first time is an abnormal waveform.
In one implementation, different first measurement items in the present embodiment correspond to different first predetermined conditions. The user may select one or more of the measurements for analysis as desired.
When the selected first measurement item is plural, as long as the value of one measurement item does not satisfy a first predetermined condition, a corresponding abnormal waveform is output. The predetermined condition corresponds to a measurement item, for example, when the measurement item is amplitude measurement, the measurement value may be an eye level, and the predetermined condition may be that the measurement value is not greater than a preset threshold value or that the measurement value is not less than a preset threshold value. According to the method and the device, the eye diagram based on the signals is combined with the historical information and the current information of the signals, the overall statistical analysis is carried out on the signals aiming at the plurality of measurement items, the problems that the accuracy is not high and the operation is not convenient when the eye diagram template analysis is used for capturing abnormal waveforms are solved, and the problems that the accuracy is not high because the eye diagram template analysis can only analyze the characteristics of the current signals according to the current information when the oscilloscope trigger function is used for capturing the abnormal waveforms is solved, so that the signal information in a time domain is lost and the accuracy is not high are solved.
According to the method for capturing the abnormal waveform, an eye pattern formed by the waveform to be detected at the first time is determined; determining a first measurement term corresponding to the eye diagram; determining a first measurement value corresponding to the first measurement item based on the eye diagram; under the condition that the first measured value does not meet the first preset condition, outputting the abnormal waveform corresponding to the first time in the eye pattern, solving the problems of low accuracy and inconvenient operation of eye pattern template analysis during abnormal waveform capture, avoiding the problem of signal information loss in a time domain caused by waveform capture by using an oscilloscope trigger function, and finally realizing the effect of accurately capturing the abnormal waveform in the signal in real time.
Fig. 2 illustrates a method for anomalous waveform capture provided by an embodiment of the invention, which may be performed by an electronic device that may include: a server or a terminal device. In other words, the method may be performed by software or hardware installed on the electronic device, the method comprising the steps of:

S202: a first measurement item corresponding to the eye diagram is determined.
The above steps may adopt the description of step S101 or step S102 in the embodiment of fig. 1, and the repeated parts are not described herein again.
