If the amplifier range of the measuring system is not set correctly, it will “clip” the signal and “chop off” the highest and lowest parts of the signal.
This is not good !
It means you are trying to turn a sine wave into a square wave.
Just as clipping is illegal in football -in data acquisition, clipping the time data will cost you by causing invalid data (spurious signals) in the frequency spectrum.
