:FUNCtion:WANalyze:ECDiff?
Syntax
:FUNCtion:WANalyze:ECDiff?
Description
Query the current frame difference.
Explanation
During the analysis based on trace, the oscilloscope compares each frame with the templet to
compute the difference value and normalizes each value using the maximum one; then, compares
the normalized value of each frame 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
the current frame and templet.
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 juged 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.
