            Indicates that memory was exhausted during frequency precalculation 
            (used to speed the process of sweep/list mode). List mode cannot
            run until either fewer frequencies have been supplied or more
            memory becomes available and the same set of frequencies are sent
            again, FREQ:MODE CW is executed, or :FREQ:MODE LIST is executed.

            error.
-321 Out of memory; Display system out of memory. An abnormal display may
     result. Memory consumption should be reduced.
            There was not enough memory in the system to properly update the
            display. Some inconsistencies may be seen. The size of any
            list/sweep should be reduced, and the source should be preset to
            clear up any inconsistencies. Report this error to service office.
