All trace modes (except zero) step through 3 states during a trace:
| State | Name | Description |
|---|
|
| 1 |
Pre Trigger Delay |
The period of time during which BitScope captures
data without enabling the trigger. The duration of this
state depends on the value in the Pre-Trigger
Delay R20. It is used to ensure BitScope
captures a minimum amount of data before a
trigger event.
|
| 2 |
Trigger Enabled |
After expiry of the Pre Trigger Delay, BitScope
continues to capture data, but now the trigger is
enabled.
It stays in this state until a trigger is seen.
|
| 3 |
Post Trigger Delay |
Upon the assertion of the trigger condition, BitScope
enters the Post Trigger Delay state where is
continues to capture data for an additional period of time
which depends on the value in the Post Trigger
Delay R11, R12.
It is used to ensure that BitScope captures a minimum
of amount of data after a trigger event.
|
By programming appropriate pre and post trigger delays (which
apply in states 1 and 3), it is possible to capture analog and
digital data before and/or (well) after the trigger event.
