A green check shows that the parameter is included in the research. If there is no green check, the
parameter will not be taken into account for the research.

Inactive research parameter

Active research parameter

Attention:

The more you select options, the longer the research.

6.1

Terrestrial mode

This mode allows automatic research on the

terrestrial

frequency band.

The table allows the selection of:



Standards



Channel widths



The channel range of the research
(i.e. 21 to 58).

The goal is to make researches
shorter.

6.2

Satellite mode

This mode allows automatic research on the

satellite

frequency band.

The table allows the selection of:



Standards



LNB bands



LNB polarizations.
