   Bases: :py:obj:`Sequence`

   Represents a Hahn-Echo sequence. 


   Build a Hahn-Echo sequence using either rectangular pulses or
   specified pulses. By default no progression is added to this sequence.


   :Parameters:

           The B0 field, in Guass

       **LO** : int or float
           The LO frequency in GHz

       **reptime** : _type_
           The shot repetition time in us

       **averages** : int
           The number of scans.
