Figure 7-7: Measurement of two equally-leveled RF sinusoidal signals with a resolution band-
width which is larger than their frequency spacing
6. Set the resolution bandwidth to 1 kHz.
The two generator signals are shown with high resolution. However, the sweep
time becomes longer. At smaller bandwidths, the noise display decreases simulta-
neously (10 dB decrease in noise floor for a decrease in bandwidth by a factor of
10).

width (1 kHz) which is significantly smaller than their frequency spacing
