Setting Up Triggers and Running Measurements
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 both state and timing modes require time tags to
reconstruct the data. These time tags will be stored either in the memory
resources of an unused pod pair, or interleaved in the data.
1. In the Trigger tab's Default Storing subtab, select the
store by default
option button and choose either
Anything
,
Nothing
,
Custom
, or
Transitions
.
Anything
means all samples are stored.
Nothing
means that no samples
are stored.
Custom
lets you specify which samples are stored.
Transitions
lets you specify which transitions to store on a per label basis.
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
(Timing mode only).
Transitional timing is a subset of store qualified timing. In transitional
timing, the store qualification is set to look for edges (transitions) on all
active channels. Active channels are those that have been assigned to a
label in the Format tab. Samples are stored for all channels whenever a
transition occurs. No other store qualification events are allowed.
For more information on store qualification in transitional timing mode,
refer to More on Store Qualification in Transitional Timing. (see page 70)
In the trigger sequence, you can override default storing for the
samples that cause actions to occur, or you can turn default storing on
or off, by inserting store actions.
