0009 Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the
0010 frontend will run a kernel thread that will periodically check for the
0011 tuner lock status and provide statistics about the quality of the
0012 signal.
0013 
0014 The information about the frontend tuner locking status can be queried
0015 using :ref:`FE_READ_STATUS`.
0016 
0017 Signal statistics are provided via
0018 :ref:`FE_GET_PROPERTY`.
0019 
0020 .. note::
0021 
0022    Most statistics require the demodulator to be fully locked
0023    (e. g. with :c:type:`FE_HAS_LOCK <fe_status>` bit set). See
0024    :ref:`Frontend statistics indicators <frontend-stat-properties>` for
0025    more details.
