Working with Scope Objects

Posttriggering (P>0)
Scope 1 triggers Scope 2 after the trigger event occurs. The following describes
some of the ways you can trigger Scope 2:
sc(2).TriggerSample = 0 Causes Scope 2 to be triggered when Scope 1
is triggered.
TP for both scopes as at the same sample.
sc(2).TriggerSample = n > 0 — Causes TP for Scope 2 to be n samples after
TP for Scope 1. Note that setting sc(2).TriggerSample to a value larger than
(N + P - 1) does not cause an error; it implies that Scope 2 will never trigger,
since Scope 1 will never acquire more than
(N + P - 1) samples after TP.
sc(2).TriggerSample = 0 < n < (N + P) — Enables you to obtain some of
the functionality that is available with pre- or posttriggering. For example,
if you have the following Scope 1 and Scope 2 settings,
- Scope 1 has
sc(1).NumPrePostSamples = 0 (no pre- or posttriggering)
- Scope 2 has
sc(2).TriggerSample = 10
- Scope 2 has sc(2).NumPrePostSample = 0
The behavior displayed by Scope 2 is equivalent to having
sc(2).TriggerSample = 0 and sc(2).NumPrePostSamples = 10.
sc(2).TriggerSample = -1Causes Scope 2 to start acquiring data from
the sample after Scope 1 stops acquiring.
