   .. py:property:: preset_monitor

      Return the averaging_time signal as the count-time preset for scan
      plans.


.. py:class:: TetrAMM

   Bases: :py:obj:`QuadEMPOLAR`

.. py:class:: QuadEMRO_mixins

   Bases: :py:obj:`ophyd.Device`


   Mixin that replaces the QuadEM trigger/preset with a no-op for read-only
   use.


   .. py:attribute:: dummy


   .. py:property:: preset_monitor

      Return a dummy signal so scan plans have a no-op preset target.


   .. py:method:: trigger()

      Immediately mark acquisition complete without driving the hardware.



   .. py:method:: stage()

      Stage using base Device logic, bypassing QuadEM staging.



   .. py:method:: unstage()

      Unstage using base Device logic, bypassing QuadEM unstaging.



.. py:class:: SydorEMRO

   Bases: :py:obj:`QuadEMRO_mixins`, :py:obj:`QuadEMPOLAR`

      stage_sigs.



.. py:class:: TetrAMMRO

   Bases: :py:obj:`QuadEMRO_mixins`, :py:obj:`TetrAMM`


   Read-only TetrAMM 4-channel electrometer that disables staging and
   triggering.


   .. py:method:: default_settings()

      Set calibration and configuration signals to config kind and clear
      stage_sigs.
