36 N9320A Spectrum Analyzer

3 Functions and Measurements

Decreasing the resolution bandwidth improves the resolution

of the individual signals and increase 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.
