QCoDeS Drivers and zhinst-toolkit¶
The Zurich Instruments drivers for QCoDeS are based on the Zurich
Instruments Toolkit. The Python package zhinst-toolkit is an extension
of the LabOne Python API ziPython. The zhinst-toolkit allows for
easier and more intuitive control of Zurich Instruments devices. For more
information, have a look at its GitHub
repository and
online documentation
Functionally, the instrument drivers for QCoDeS work in the same way as the
drivers available in the zhinst-toolkit. However, they implement the
instrument drivers, their submodules and parameters into the QCoDeS
measurement framework by subclassing or wrapping elements from QCoDeS. Those
include the QCoDeS classes
qcodes.instrument.base.Instrument:for instrument drivers, e.g. the zhinst.qcodes.HDAWG
qcodes.instrument.channel.InstrumentChannel:for submodules, i.e. nodes in the device’s nodetree structure or device-specific modules such as AWG Cores, Readout Channels, Data Aqcuisition Modules, Sweeper Module
qcodes.instrument.parameter.Parameter:for device parameters that mostly correspond directly to device settings, using the LabOne Python API they would be accessed with a unique node path, e.g. ‘dev1234/sigouts/0/enable’
