Chapter 2: Task Guide
To select transitional timing or store qualified
not look for a trigger until the specified percentage of pretrigger data
has been stored. After a trigger has been detected, the specified
percentage of posttrigger data is stored before the analyzer halts.
In State and Transitional Store Qualified modes, when a Run is started,
the analyzer immediately looks for the trigger condition. In other
words, the trigger position setting specifies the maximum amount of
data that should be stored before the trigger.
To set acquisition memory depth
If you need less data and want measurements to run faster, you can
limit the number of samples that are stored in logic analyzer acquisition
memory.
1. In the Sampling tab (or in the Settings subtab of the Trigger tab), select
the acquisition depth.
The number of samples that can be chosen for the Acquisition Depth are
approximations. The combination of count tags, pod assignments, and
configuration modes affect what choices are available.
To name an analyzer
You can give more descriptive names to a logic analyzer.
1. In the Sampling tab, select the Analyzer Name field.
2. Enter the new name.
The name now appears below the instrument tool icon in the workspace.
You can also name analyzers in the “Pod Assignment Dialog” on
page 130.
To turn an analyzer off or on
You may want to turn an analyzer off if you don't want it to be included
in further measurements.
To turn an analyzer off
1. In the Sampling tab, select the On box that is checked.
