WebTherefore, FFT mode proves shorter sweep times than the swept mode in narrow spans. The difference in speed is more pronounced when the RBW filter is narrow when measuring low-level signals. In the FFT mode, the sweep time for a 20 MHz span and 1 kHz RBW is 747.3 ms compared to 24.11 s for the swept mode as shown in Figure 18 below.
