Labber-QUA integration
Setting up the python environment#
Labber allows using a custom python environment for instrument drivers. This is required
as the QM package needs to be inclued in the driver file.
To set up the custom environment, we recommend using python 3.7 and installing the following dependencies specified on the Labber documentation:
In addition, the qm python package should be installed.
When the environment is set, point the Python distribution field (under preferencees->advanced)
in Labber to your environment's pythonw.exe (on windows) or 'python.exe'
file. More details are found on Labber's documentation.
Including the driver in the instrument list#
Copy the OPX folder from this repository to the location of your driver files.
This is typically in ~\Labber\Drivers your user folder, but you can check the
Local drivers path inside configuration->folders in Labber. See Labber's documentation for
further details.
OPX Labber driver structure#
Labber drivers are defined in an .ini files which describes the inputs and outputs of the device and
a .py file specifying the functions which can be performed and the connection procedure to the device.
The qua configuration can be specified as a json file in the configuration parameter. A config.json
file that is suitable for the QUA programs in this driver is included.
The .py file defines two function, qua_prog_1 and qua_prog_2 which return QUA programs.
Each program has two parameters: amplitude and frequency. There is one output: the Signal which is the QUA simulator signal output.
This combination of parameters can be used to set up a simple sequence in the measurement-editor.
Note about Labber and the OPX driver#
Note that as the OPX runs QUA programs which are very flexible in terms of inputs and outputs, each modification to QUA programs will probably require modifications to the driver and possibly to the ini files.
