Resolving Signals of Equal Amplitude

4. Since the resolution bandwidth must be less than or equal to the
frequency separation of the two signals, a resolution bandwidth of
100 kHz must be used. Change the resolution bandwidth to 100 kHz
by pressing
BW/Avg, Res BW, 100, kHz. The peak of the signal has
become flattened indicating that two signals may be present as
shown in Figure 1-6. Use the knob or step keys to further reduce the
resolution bandwidth and better resolve the signals.
