This is the QCoDeS driver for the Rohde & Schwarz SGS100A signal generator.
Status: beta-version.
.. todo::
- Add all parameters that are in the manual
- Add test suite
- See if there can be a common driver for RS mw sources from which
different models inherit
This driver will most likely work for multiple Rohde & Schwarz sources.
it would be a good idea to group all similar RS drivers together in one
module.
Tested working with
- RS_SGS100A
This driver does not contain all commands available for the RS_SGS100A but
only the ones most commonly used.
