    """The TRIGGER_SETTINGS_MDO3XXX node sets advanced trigger settings.

    Note that "unchanged" will leave the settings unchanged.

    Requires a CONNECTION_MDO3XXX node at the start of the app to connect with
    the instrument. The VISA address will then be listed under 'connection'.

    This node should also work with compatible Tektronix scopes (untested):
    MDO4xxx, MSO4xxx, and DPO4xxx.

    Parameters
    ----------
    connection: VisaConnection
        The VISA address (requires the CONNECTION_MDO3XXX node).
    query_set: str
        Whether to query or set the triggering channel.
    edge_couplings: str
        Set the trigger edge coupling type.
    trigger_types: str
        Set to trigger on edge, logic, or pulses.
    edge_slope: str
        Set to trigger on positive, negative, or either slopes.

    Returns
    -------
    DataContainer
        TextBlob: Summary of trigger settings.
