Figure 60 The Shown Frequency of M Selecting an FFT Window m The FFT feature provides four windows Each is a trade off between frequency resolution and magnitude accuracy What you want to measure and your source signal characteristics help 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 1s the best type for measuring the frequency spectrum of nonrepetitive signals and Rectangle 8 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 69 OS Series Handheld DSO amp DMM 8 Advanced Function of Oscilloscope 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 Hamming 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
