The FFT feature provides four windows Each one is a trade off between frequency resolution and magnitude accuracy What you want to measure and your source signal 35 User Manual of OWON Color Mixed Signal Digital Storage Oscilloscope characteristics help you to determine which window to use Use the following guidelines to select the best window This is the best type of window for resolving frequencies that are very close to the same value but worst for accurately measuring the amplitude of those frequencies It is the best type for measuring the frequency spectrum of nonrepetitive signals and measuring frequency components near DC Use rectangle for measuring transients or bursts where the signal level before and after the event are nearly equal Also use this window for equal amplitude sine waves with frequencies that are very close and for broadband random noise with a relatively slow varying spectrum This is a very good window for resolving frequencies that are very close to the same value with somewhat improved amplitude accuracy over the rectangle window It has a slightly better frequency resolution than the Hanning Use Hamming for measuring sine periodic and narrow band random noise This window works on transients or bursts where the signal levels before and after the event are significantly different This is a very good window for measuring amplitude accuracy but less so for resolving frequencies Use H
