14.6.1
Tuner-1
– Main
In this page it is possible to set the behavior of the Tuner-1 and each single parameter it is reported below:
14.6.2
Tuning Mode
By using this parameter it is possible to change the tuning mode that should be OFF
–
Static
–
Scan
–
Smart Scan.
OFF
In OFF the tuner is unavailable
STATIC
in Static the tuner remain fixed on a single frequency that is depending by
the parameter Static Channel Index
SCAN
In Scan mode the tuner starts to scan the FM band, from channel 1 up to
the <Last Channel Scanning Index>
SMART SCAN
In smart mode the channel scan time is adjusted automatically according
to instantaneous measurements requirements.
14.6.3
Smart Scan
The smart scan
is an scan evolution method and “smart” mode to check each single parameter of the checked
frequency: if during a scan, a single parameter of the scanned frequency is out-of-range the Wolf 2MS should decide to
remain more time (in seconds) on the checked frequency, in order to get the correct value, or exclude a false-positive
alarm.
Practical example: a typical case should be the decoding of the ODA service in RDS, or a PI Code, or any value
checked. If the decoding gives an “error” the Wolf 2MS can stay more seconds on this frequency, and wait in order to get
the correct value, and don’t generate an error (via snmp trap) that can overload the NMS system. In the real fact the
checked valued is correct, but sometimes due to a lot of unpredictable situation, this value should be considered as an
error.
