FREQUENCY SPAN

Figure 5-1. Relationship Between Frequency Span, Sweep Time, and Number of Points

Note the following in the graph above:

As the frequency span decreases, the sweep time generally decreases.

As the number of points decreases, the sweep time decreases.

If you are viewing both measurement channels but only need one, you can
decrease measurement time by turning one of the channels off.

Select the channel you wish to turn off with either the

button. Then select
