4 Change the resolution bandwidth (RBW) to 100 kHz so that

the RBW setting is less than or equal to the frequency

separation of the two signals:

Press > 100 > kHz

Notice that the peak of the signal has become flattened

indicating that two signals are present.

5 Decrease the video bandwidth to 3 kHz:

Press > Video BW > 3 > kHz

Two signals are now visible as shown in Figure 6. Use the

front- panel knob or arrow keys to further reduce the

resolution bandwidth and better resolve the signals.
