How to get the resolution bandwidth of an older, saved trace on an OSA (optical spectrum analyzer)

To utilize this optical spectrum analyzer function, first, use the :MEMory:LOAD command to load a command from the memory. Then, use the SENSE:BANDWIDTH:RESOLUTION? to get the resolution of the loaded trace.
