Figure 3-12: Measurement of two equally-leveled RF sinusoidal signals with a resolution band-
width which is larger than their frequency spacing
Note: Reducing the resolution bandwidth. The resolution bandwidth (RBW) can be
reduced again by turning the rotary knob counterclockwise, thus yielding a higher
frequency resolution.
6. Set the resolution bandwidth to 1 kHz. To do so, in the bandwidth menu, press the
"Res BW Manual" softkey and enter 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).
