    Describes how to handle `Acquisitions` that write to the same `AcquisitionIndex`.

    A BinMode is a property of an `AcquisitionChannel` that describes how to
    handle multiple
    :class:`~quantify_scheduler.operations.acquisition_library.Acquisition` s
    that write data to the same `AcquisitionIndex` on a channel.

    The most common use-case for this is when iterating over multiple
    repetitions of a :class:`~quantify_scheduler.schedules.schedule.Schedule`
    When the BinMode is set to `APPEND` new entries will be added as a list
    along the `repetitions` dimension.

    When the BinMode is set to `AVERAGE` the outcomes are averaged together
    into one value.

    Note that not all `AcquisitionProtocols` and backends support all possible
    BinModes. For more information, please see the :ref:`sec-acquisition-protocols`
    reference guide and some of the Qblox-specific :ref:`acquisition details
    <sec-qblox-acquisition-details>`.
