To Widen the System Bandwidth

1. Press
Avg IF BW
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
Avg AVG FACTOR
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
Menu NUMBER OF POINTS
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
Sweep Setup
2. Select the sweep type:
• Select
LIN FREQ
• Select

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.
