To specify default storing
You can set up default storing so that only the data samples you're
interested in are saved in logic analyzer acquisition memory.
NOTE: Default storing in the timing sampling mode's 400 MHz / 32M Sample
Transitional or Store Qualified configuration requires time tags to be stored
with each stored data sample in order for all sampled values to be
reconstructed and displayed later. If all data pods are used, memory depth is
reduced by half in order to store the required time tags.
1. In the Trigger tab's Default Storing subtab, select the Store by default
option button and choose:
• Anything to store all samples.
• Nothing to store no samples.
• Custom to specify which samples are stored.
• Transitions (only available in the timing sampling mode's 400 MHz /
32M Sample Transitional or Store Qualified configuration) to store
a sample only if it's different than the previously stored sample.
2. If you chose Custom:
a. Select the Store if or Store if NOT option.
b. Specify events that identify the states to be stored or not stored.
c. If you would like to specify the evaluation order of the event list, select
Group events. Then, in the Group Events dialog, either select the Add
parens button to group events or select the Remove parens button to
ungroup events. When you're done grouping events, select the OK
button.
3. If you chose Transitions and you would like to further qualify storage of
transitions by ignoring data changes on particular labels (for example, if
there's a high occurrence of transitions on labels that are meaningless in
