 Another important feature is the possibility to save and load device working points. To store a certain configuration as your default working point,
 use device.save_defaults. This stores all parameter values (of parameters that can be set). With device.set_defaults() you can reset it to the stored
 configuration. Alternatively you can use "device.save_state(name)" and "device.set_state(name)" to store and set multiple working points with
-custom names. They can also be accessed via "device.states" in case you forgot the name. 
+custom names. They can also be accessed via "device.states" in case you forgot the name.
 For all of those methods the parameters are ramped to the final state by default (with the default QuMada ramp rate). You can use the argument "ramp = False" to avoid this, or use keyword
 arguments (ramp_rate, duration) to adjust the ramp speed when calling the methods. Alternatively, you can set the parameter "device.ramp" to True or False in order to control the behaviour
 for the complete device.
