Quick Scanning Stage
The quick scanning stage skips though the frequency range at intervals
depending on the resolution, and measures the signal level at each
interval. The signal level is taken as the maximum level at all available
antenna inputs and is plotted on the on screen display.
A chequered bar will move along the frequency axis representing the
current progress.
This stage is necessary for the service scanning stage, however if the
users’ aim is to check for noise free frequencies to put their service on,
then the scan could be stopped at whatever point by pressing the
MODE button.
Service Scanning Stage
The service scanning stage jumps between the strongest signal levels
detected and checks for a decodable service.
If a service is found, signals around it will be ignored to save scanning
time as they are mostly likely part of the service. The number of
surrounding signals ignored depends on the bandwidth of the service
found.
Once a scan is finished, services found will be marked by a chequered
bar and stored. If a scan is stopped early the services found so far will
be marked and stored.
Note: If the receiver is in Narrowband mode only Narrowband services will be detected as
decodable. If the receiver is in DVB-T mode only DVB-T services will be detected.
