3.3.3.2.2.1.5.- ECHOES

The

ECHOES

option makes it possible to visualise the time response of the

DVB-T

channel.

This function is very useful to find out if the signal we are receiving comes from a single main
beam or if a series of secondary beams have been added with different delays and bandwidths.
This will often help to explain why the BER does not have an acceptable value if we have a good
C/N and signal level.

Within the echo visualisation mode there is a menu that allows us to select the x-axis units
between microseconds or kilometres. Depending on the unit selected, the zoom menu will allow
us to vary the visualisation window between the following values:

-
