REW is the best way to do sweeps, once you get it set up. Its not that complicated, but there is a learning curve.
What is "REW" ? Can someone (not too) briefly explain the process and what is needed to get this graph info? Does this process give you a graph, or just individual data points you manually put onto a graph? I assume you need a laptop (not Mac), a RS SPL meter and this 'REW'. (working to abolish [my] ignorance.;o)
