search_settable_param(instrument: qcodes.instrument.base.InstrumentBase, nested_parameter_name: str) → qcodes.instrument.Parameter

Searches for a settable parameter of an instrument when it is in a nested hierarchical form such as instrument.submodule_1.channel_1.parameter

Parameters

• instrument – The root QCoDeS instrument where the parameter resides.

• nested_parameter_name – Hierarchical nested parameter name.

Return type

Parameter

lazy_set(instrument: qcodes.instrument.base.InstrumentBase, parameter_name: str, val: Any) → None

Sets the value of a QCoDeS parameter only if it is different from the value in cache.

Parameters

• instrument – The QCoDeS instrument to set the parameter on.

• parameter_name – Name of the parameter to set.

• val – Value to set it to.

check_already_existing_acquisition(new_dataset: xarray.Dataset, current_dataset: xarray.Dataset)

Checks whether there is any data which is at the same coordinate in new_dataset and current_dataset. If there is, it will raise an error.

Parameters

• new_dataset – New dataset.

• current_dataset – Current dataset.
