3. Start
Press the Satrt softkey or press the Run/Stop key to enable waveform
analysis. Note that during the analysis process, the progress bar is displayed and
the parameters can not be modified. After the analysis finishes, the analysis
results of “Error Frames”, “Current Error” and “CurFrame Diff” are displayed, at
the same time, the first error frame is located, as shown in the figure below. At
this point, using menu can locate the next error frame, the previous error frame
as well as every frame in this waveform analysis.
Error Frames: the total number of error frames discovered in this analysis.
Current Error: the order number of the error frame lately located in all the
error frames when locating every data frame in this analysis.
CurFrame Diff:
During the analysis based on trace, the scope compares each frame with the
templet to compute the difference value and normalizes each value using the
maximum one, then, compares the normalized value with the threshold selected
to judge whether the frame is an error frame. “CurFrame Diff” (relative
difference) is the normalized value of the difference between current frame and
templet.
During the analysis based on pass/fail mask, the scope compares each frame
with the mask to compute the difference value and recognizes the frame whose
difference value is equal to or larger than the threshold selected as an error
frame and the corresponding “CurFrame Diff” is 99%. The “CurFrame Diff” of
other frames is 0%. Note, there are only two “CurFrame Diff” values, 99% and
0%, under the analysis based on pass/fail mask.
4. Cancel
During the analysis, users can press the Cancel softkey to stop the analysis and
press the Start softkey again to restart the analysis.
