To Set the Auto Sweep Time Mode

Auto sweep time mode is the default mode (the preset mode). This mode maintains the
fastest sweep speed possible for the current measurement settings.
• Press
Sweep Setup

To Widen the System Bandwidth

1. Press
IF BW
Avg
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 FACTOR
Avg
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
NUMBER OF POINTS
Menu
2. Enter a number of points that is less than the value displayed on the analyzer screen
and press .
x1
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
