Represents the HP 11713A Switch and Attenuator Driver and provides a high-level
interface for interacting with the instrument.
Usually an attenuator is hooked to either X or Y or X and Y. To ease the control
of the attenuator driver you have the possibility to set an attenuator type via
the attribute 'ATTENUATOR_X' or 'ATTENUATOR_Y'. The hp11713a keeps different default attenuator
mappings. After setting the attenuator type you are able to use the methods 'attenuation_x'
and/or 'attenuation_y' to set the switch driver to the correct value for the specified
attenuation. The attenuation values are rounded.
