36 N9320A Spectrum Analyzer
3 Functions and Measurements
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.
Decreasing the resolution bandwidth improves the resolution
of the individual signals and increases the sweep time.
Figure 6 Resolving Signals of Equal Amplitude
For fastest measurement times, use the widest possible
resolution bandwidth. Under factory preset conditions, the
resolution bandwidth is coupled to the span.
