 6Querying frontend status and statistics
 7***************************************

 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`.

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.
