belongs to carriers and the X-axis to time. Therefore a colour map is showed on the
display, see figure below.
Any MER level could be displayed at any time reference using cursors. This tool is
especially useful when a MER level analysis is going to be processed during a long
period of time. When the process is finished the capture could be showed and any
anomaly will be easily detected at any time.
Only DVB-T, DVB-T2 and DVB-H signals could be used with this function.
