15. Set the RBW to 30 kHz. The RBW
setting is located at the left side of the
spectrum display.
TIP. RBW
The resolution bandwidth (RBW)
determines the fast Fourier transform
(FFT) bin size, or the smallest
frequency that can be resolved.
Smaller RBW improves the
selectivity, but degrades the sweep
speed and the trace update rate.
