Chapter 2: Task Guide
To select transitional timing or store qualified
actions to reset or increment a counter. You can insert counter events
in a different sequence level to test the value of a counter.
To insert a counter action
1. In the Trigger tab's Trigger Sequence area, select one of the action buttons
(for example, Trigger or Goto), choose
Insert ACTION
, choose
Counter
,
and choose either
Reset
or
Increment
.
To insert a counter event
Counter events are like other
events
in that they evaluate to either true
or false.
1. In the Trigger tab's Trigger Sequence area, select one of the existing event
buttons (for example, a label name, Anything, Timer, Counter, or Flag) and
choose to insert or replace a
Counter
.
2. Select the counter number button and choose the number of the counter
you want to test.
3. Select the operator button and choose either
>=
or
<
.
4. Enter the counter value.
To insert flag actions/events
Flags can be used to signal between modules in the logic analysis
system mainframe, an expansion frame, or in multiple frames
connected with the multiframe module.
There are 4 flags that are shared across all connected logic analysis
system frames. A flag may be driven or received by multiple modules.
Using flags, logic analyzer modules can communicate back and forth
with each other multiple times during a data acquisition, both before
and after their trigger events occur. (By comparison, the Intermodule
window lets one module arm another module one time when its trigger
occurs.)
By default, flags are cleared. You can insert
actions
to set, clear, pulse
set, or pulse clear a flag. You can insert flag
events
in different logic
analyzer modules to test whether a flag is set or clear.
