        Waits for the measurement or generation to complete.

        Use this method to ensure that the specified operation is complete
        before you stop the task.

        Args:
            timeout (Optional[float]): Specifies the maximum amount of time in
                seconds to wait for the measurement or generation to complete.
                This method returns an error if the time elapses. The
                default is 10. If you set timeout (sec) to
                nidaqmx.WAIT_INFINITELY, the method waits indefinitely. If you
                set timeout (sec) to 0, the method checks once and returns
                an error if the measurement or generation is not done.
