My RIGOL DS1102E has math functions including one that works reasonably 
has a spectrum analyzer. The screen splits top and bottom with the SA 
being half. t would be nice (haven't researched) to use the full screen 
for the SA.

I plan on feeding a White/P/R/Brown  noise source to see what the SA 
shows. But there are other things higher priority.
