Advanced Echoes with pre and post echoes analysis

The Echoes option in BSA331 makes it possible to visualize the impulse 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 bean 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 acceptable value if we have a good C/N and signal level.

Within the echoes visualisation mode there is a menu that allows us to select the x-axis units between microseconds or kilometers.

Depending on the unit selected, the zoom menu will allow us to vary the visualisation window between the following values:

The echoes graphics can been saved as a Glog.
