The vertical axis shows the available link power margin in dB. The measured values only
have the required accuracy to be able to show the existing link power margin correctly in the
range from 0 dB to 6 dB.
The horizontal axis shows the time since the IE switch started up relative to the current time
of day and the current date. Date and time information are adopted from the PC on which the
Web browser in use is running.
