How to use the nitclk._visatype.ViReal64 function in nitclk

session.channels[0,1]._get_attribute_vi_real64(attribute_id)

        Args:

                sample_clock_delay


        Returns:
            value (float): The value that you are getting

This method requires repeated capabilities. If called directly on the
        nitclk.Session object, then the method will use all repeated capabilities in the session.
        You can specify a subset of repeated capabilities using the Python index notation on an
        nitclk.Session repeated capabilities container, and calling this method on the result.

        Args:
            attribute_id (int): The ID of the property that you want to set Supported Property
                sample_clock_delay

            value (float): The value for the property

        '''
