Tektronix TBS1072B User Manual

The FFT function includes three FFT Window options. There is a trade-off
between frequency resolution and amplitude accuracy with each type of window.
What you want to measure and your source signal characteristics will help you to
determine which window to use.
Window Measure Characteristics
Hanning Periodic waveforms Better frequency, poorer magnitude accuracy
than Flattop
Flattop Periodic waveforms Better magnitude, poorer frequency accuracy
than Hanning
Rectangular Pulses or transients Special-purpose window for waveforms that do
not have discontinuities. This is essentially the
same as no window
