      9Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the
     10frontend will run a kernel thread that will periodically check for the
     11tuner lock status and provide statistics about the quality of the
     12signal.
     13
     14The information about the frontend tuner locking status can be queried
     15using :ref:`FE_READ_STATUS`.
     16
     17Signal statistics are provided via
     18:ref:`FE_GET_PROPERTY`.
     19
     20.. note::
     21
     22   Most statistics require the demodulator to be fully locked
     23   (e. g. with :c:type:`FE_HAS_LOCK <fe_status>` bit set). See
     24   :ref:`Frontend statistics indicators <frontend-stat-properties>` for
     25   more details.
