SDATa: Complex measurement data. The returned numbers (which are
independent of the Graph Type that is associated with the trace) are the
complex measurement data (Real and Imaginary) for each point of the
trace. A 551 point trace therefore has a total of 1102 points that get
transferred.
FMEM: Formatted (or Final) Memory data. Similar to FDATa, but for
memory data.
SMEM: Complex memory data. Similar to SDATa, but for memory
data.
Note that in order to get valid data when querying for memory data, you
must first store a trace into memory using the command
CALC:MATH:MEMorize. The format of the block data that is returned
can be specified by the command :FORMat:DATA. The response
begins with an ASCII header that specifies the number of data bytes. It
appears in the format #AX, where A is the number of digits in X,
and X is the number of bytes that follow the header. Each data point is
separated by a comma delimiter.
