gettables ========= .. py:module:: quantify_scheduler.gettables .. autoapi-nested-parse:: Module containing :class:`quantify_core.measurement.types.Gettable`\s for use with quantify-scheduler. .. warning:: The gettable module is expected to change significantly as the acquisition protocols (#36 and #80) get fully supported by the scheduler. Currently different Gettables are required for different acquisition modes. The intent is to have one generic ``ScheduleGettable``. Expect breaking changes.

The gettable evaluates the parameters passed as ``schedule_kwargs``, then generates the :class:`quantify_scheduler.schedules.schedule.Schedule` using the ``schedule_function``, this is then compiled and finally executed by the :class:`~.InstrumentCoordinator`. ``ScheduleGettable`` can be set to return either static (demodulated) I and Q values or magnitude and phase. :param quantum_device: The qcodes instrument representing the quantum device under test (DUT) containing quantum device properties and setup configuration information. :param schedule_function: A function which returns a :class:`quantify_scheduler.schedules.schedule.Schedule`. The function is required to have the ``repetitions`` keyword argument. :param schedule_kwargs: The schedule function keyword arguments, when a value in this dictionary is a :class:`~qcodes.instrument.parameter.Parameter`, this parameter will be evaluated every time :code:`.get()` is called before being passed to the :code:`schedule_function`. :param num_channels: The number of channels to expect in the acquisition data. :param data_labels: Allows to specify custom labels. Needs to be precisely 2*num_channels if specified. The order is [Voltage I 0, Voltage Q 0, Voltage I 1, Voltage Q 1, ...], in case real_imag==True, otherwise [Magnitude 0, Phase 0, Magnitude 1, Phase 1, ...]. :param real_imag: If true, the gettable returns I, Q values. Otherwise, magnitude and phase (degrees) are returned. :param batched: Used to indicate if the experiment is performed in batches or in an iterative fashion. :param max_batch_size: Determines the maximum number of points to acquire when acquiring in batched mode. Can be used to split up a program in parts if required due to hardware constraints. :param always_initialize: If True, then reinitialize the schedule on each invocation of ``get``. If False, then only initialize the first invocation of ``get``. .. py:attribute:: _data_labels_specified .. py:attribute:: always_initialize .. py:attribute:: is_initialized :value: False .. py:attribute:: _compiled_schedule :type: quantify_scheduler.schedules.schedule.CompiledSchedule | None :value: None .. py:attribute:: real_imag .. py:attribute:: batched .. py:attribute:: batch_size .. py:attribute:: _return_xarray .. py:attribute:: schedule_function .. py:attribute:: schedule_kwargs .. py:attribute:: _evaluated_sched_kwargs .. py:attribute:: quantum_device .. py:attribute:: _backend :value: None .. py:attribute:: _debug_mode :type: bool :value: False .. py:method:: _compile(sched: quantify_scheduler.schedules.schedule.Schedule) -> None Compile schedule, separated to allow for profiling compilation duration. .. py:method:: initialize() -> None Generates the schedule and uploads the compiled instructions to the hardware using the instrument coordinator. .. py:property:: compiled_schedule :type: quantify_scheduler.schedules.schedule.CompiledSchedule | None Return the schedule used in this class. .. py:method:: get() -> tuple[numpy.ndarray, Ellipsis] Start the experimental sequence and retrieve acquisition data. The data format returned is dependent on the type of acquisitions used in the schedule. These data formats can be found in the :ref:`user guide `. :returns: A tuple of acquisition data per acquisition channel as specified above. .. py:method:: initialize_and_get_with_report() -> str Create a report that saves all information from this experiment in a zipfile. Run :meth:`~.ScheduleGettable.initialize` and :meth:`~.ScheduleGettable.get` and capture all information from the experiment in a zipfile in the quantify datadir. The basic information in the report includes the schedule, device config and hardware config. The method attempts to compile the schedule, and if it succeeds, it runs the experiment and adds the compiled schedule, a snapshot of the instruments, and logs from the actual hardware (only Qblox instruments supported currently) to the zipfile. A full error trace is also included if any of these steps fail. :returns: A path to the generated report. Directory name includes a flag indicating at which state the experiment and report retrieval stopped. Flags (defined in :func: `~._generate_diagnostics_report`): - ``failed_initialization``: The experiment failed during :meth:`~.ScheduleGettable.initialize`. - ``failed_exp``: The experiment initialized failed during :meth:`~.ScheduleGettable.get`. - ``failed_connection_to_hw``: The experiment initialized but both :meth:`~.ScheduleGettable.get` and :meth:`~.InstrumentCoordinator.retrieve_hardware_logs` failed. Connection to hardware was likely interrupted during runtime. - ``failed_hw_log_retrieval``: The experiment succeeded but :meth:`~.InstrumentCoordinator.retrieve_hardware_logs` failed. - ``completed_exp``: The experiment succeeded. .. py:function:: _evaluate_parameter_dict(parameters: dict[str, Any]) -> dict[str, Any] Loop over the keys and values in a dict and replaces parameters with their current value. :param parameters: A dictionary containing a mix of :class:`~qcodes.instrument.parameter.Parameter`\s and normal values. :returns: The ``parameters`` dictionary, but with the parameters replaced by their current value. :raises TypeError: If a parameter returns None
