Note:
The memory trace is bit-mapped into the picture memory. Therefore, when the memory
trace is recalled, it will not be adapted to any modifications of the reference level or span
that may have been made in the meantime.
When a stored data set is called, the R&S FSH stores the associated trace in the trace
memory. The stored trace can be displayed with SHOW MEMORY.
