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.
