Hello all!
Really enjoying learning to use REW but I am having some repeatability issues.
If I run repeated measurements they don't come out the same, specifically in the 10-40 Hz range, plus a few spikes in the 100 to 500 Hz range tend to pop in and out.
If I use a loop-back (and no cal file) all is well.
I can't see how I can set up my sub if I can't get consistant results.
the plots are:
green=looped
and three consecutive measurements with C weighting and the correct cal file for my SPL meter.
Thanks!
Tom
