I just picked up a scanner, and it displays all sorts of info... More than I expected, to be honest. One of the parameters it showed me is LTFT B1 and LTFT B2, and STFT B1 and STFT B2. Here's the thing though... I can't find much info on them. I wouldn't usually mind, but mine is showing -0.3 on LTFT B1 and 1.8 on LTFT B2. Is this significant? Does it matter? And what does it mean? Can anybody explain all this to me?
