Optimizing Measurement Results
Increasing Sweep Speed
To Widen the System Bandwidth
1. Press .
2. Increase the IF bandwidth to increase the sweep speed.
The specifications and characteristics chapter of the reference guide shows the relative increase in
sweep time as you decrease system bandwidth.
To Reduce the Averaging Factor
By reducing the averaging factor (number of sweeps) or switching averaging off, you can increase the
analyzer's measurement speed. The time needed to compute averages can also slow the sweep time
slightly, in narrow spans.
1. Press .
2. Enter an averaging factor that is less than the value displayed on the analyzer screen and press .
3. If you want to switch off averaging, press .
To Reduce the Number of Measurement Points
1. Press .
2. Enter a number of points that is less than the value displayed on the analyzer screen and press .
Refer to the “Specifications and Characteristics” chapter of the reference guide for examples of how sweep
time changes with the number of points.
To Set the Sweep Type
Different sweep speeds are associated with the following three types of non-power sweeps. Choose the
sweep type that is most appropriate for your application.
1. Press .
2. Select the sweep type:
• Select for the fastest sweep for a given number of fixed points.
• Select for the fastest sweep when specific non-linearly spaced frequency points are
of interest.
• Select for the fastest sweep when the frequency points of interest are in the lower
part of the frequency span selected.
To View a Single Measurement Channel
Viewing a single channel will increase the measurement speed if the analyzer's channels are in alternate, or
uncoupled mode.
1. Press .
2. Press and to alternately view the two measurement channels.
