    Returns complex value of UHFQA Monitor nodes.

    This acquisition resolver corresponds to measuring a time trace of the input on the
    I channel (input 1) and Q channel (input 2).

    ----------
    uhfqa
    monitor_nodes
    """
    (node_i, node_q) = monitor_nodes

    Returns complex value of UHFQA Result nodes.

    Note that it needs two nodes to return a complex valued result.
