(refer to the setting method of the current frame mentioned above) and the
default is the first frame.
 End Frame: press this key to set the end frame of waveform analysis (refer
to the setting method of the current frame mentioned above) and the
default is the last frame.
 Threshold: press this key to set the threshold of waveform analysis and the
range is from 1% to 99%. The threshold is used to judge whether the frame
is an error frame. A frame is recognize as an error one if the (relative)
difference value between the frame and the templet is equal to or larger
than the threshold currently set.
9. Time Tag
The time tag is used to display the absolute recording time of each frame of the
waveform currently recorded. Press Time Tag to enable or disable the time tag
function. When it is enabled, the time tag information is displayed at the upper
right corner of the screen as shown in the figure below.
T
0
: display the absolute starting time of the waveform record.
△T: display the recording time deviation of the current waveform relative to the
first frame of waveform.
