3.4 Occupied BW Measurement

3.4.10.1 Select Trace

Specifies the selected trace, which is the trace that will be affected when you

change trace settings.

Select Trace appears above the menu panel, indicating that it applies to all controls

in the menu panel. Select Trace is blanked if you select a tab whose controls do not

depend on the selected trace (for example, Trace Function).

Notes The selected trace is remembered even when not in the Trace menu

Dependencies For the Swept SA measurement:

–

In Image Suppress mode, when you select a trace it becomes the active trace, and the formerly

active trace goes into View

–

When you turn on Image Suppress, Update turns off for all traces except the selected trace

For the ACP measurement, when Meas Method is RBW, FAST or FPOWer, Select Trace is disabled

Preset Trace 1

State Saved Yes

3.4.10.2 Trace Control

The controls on this tab allow you to set the "Trace Type" on page 1927 and its

update mode.

There are four Trace Types:

–

Clear/Write

–

Trace Average

–

Max Hold

–

Min Hold

Each type handles data in a different way.

Each trace also has two values that determine whether it is being written or not, and

whether it is being displayed or not. These values, Update and Display, are

described fully in the "View/Blank" on page 1740 control description. Essentially,

when Update is ON, a trace is updating, and when Update is OFF it is not. When

Display is ON, it is visible and when Display is OFF it is not. These terms are used

throughout the descriptions in this section.
