This may be useful to minimize the required bandwidth. However, be aware that if the window does not contain exactly one period of your signal, heavy sidelobes may occur, which do not exist in the original signal.

The size of the window can be defined manually according to the record length, the overlap factor, and the FFT length. An FFT overlap of 67%, for example, means the second FFT calculation uses the last 67% of the data of the first FFT.

Page 87 ® Configuration R&S FSV/A3000 I/Q Analyzer Adjusting Settings Automatically Remote command: on page 202 [SENSe:]ADJust:FREQuency Setting the Reference Level Automatically ( Auto Level ) Automatically determines a reference level which ensures that no overload occurs at the R&S FSV/A for the current input data. At the same time, the internal attenuators are adjusted so the signal-to-noise ratio is optimized, while signal compression and clipping are minimized.
Page 88 ® Configuration R&S FSV/A3000 I/Q Analyzer Adjusting Settings Automatically Lower Level Hysteresis When the reference level is adjusted automatically using the Auto Level function, the internal attenuators and the preamplifier are also adjusted. To avoid frequent adapta- tion due to small changes in the input signal, you can define a hysteresis. This setting defines a lower threshold the signal must fall below (compared to the last measure- ment) before the reference level is adapted automatically.
