Select NIT: The 'Select NIT' drop-down menu shows NIT tables available

in the transport stream currently being analysed. Information

in the selected NIT will be used to generate a tuning list

when the Import tunings button is clicked.

Naming policy: The probe will automatically name tunings according to the

naming policy selected by the user: 'Frequency', 'TS ID' or

'TS ID and frequency'.

tunings that are already present in the tuning list will be

renamed in accordance with the naming policy selected by

the user.

round-robin loop unless the 'Disable tuning' box is checked.
