 A non-AreaDetector `StandardDetector` should implement `DetectorControl` and `DetectorWriter` directly.
 Here we construct a `DetectorControl` that co-ordinates signals on a PandA PositionCapture block - a child device "pcap" of the `StandardDetector` implementation, analogous to the :py:class:`FooDriver`.

 The PandA may write a number of fields, and the :py:class:`PandaHDFWriter` co-ordinates those, configures the filewriter and describes the data for the RunEngine.

 The PandA StandardDetector implementation simply ties the component parts and its child devices together.
