| Querying frontend status and statistics | |
| *************************************** | |
| Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the | |
| frontend will run a kernel thread that will periodically check for the | |
| tuner lock status and provide statistics about the quality of the | |
| signal. | |
| The information about the frontend tuner locking status can be queried | |
| using :ref:`FE_READ_STATUS`. | |
| Signal statistics are provided via | |
| :ref:`FE_GET_PROPERTY`. | |
| .. note:: | |
| Most statistics require the demodulator to be fully locked | |
| (e. g. with :c:type:`FE_HAS_LOCK <fe_status>` bit set). See | |
| :ref:`Frontend statistics indicators <frontend-stat-properties>` for | |
| more details. |
