3. Start
Press Start to enable waveform analysis. Note that during the analysis process,
the progress bar is displayed and the parameters cannot 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. The
number of error frames is related to the error frame threshold currently set.
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 oscilloscope compares each frame

of data with the template 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 template.
During the analysis based on pass/fail mask, the oscilloscope 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 100%;
otherwise, the frame is judged as correct and the "CurFrame Diff" is 0%.
Note: There are only two "CurFrame Diff" values (100% and 0%) under the
analysis based on pass/fail mask.
