trigger (xPC Target)

Software trigger the start of data acquisition for one or more scopes.

Syntax

MATLAB command line

trigger(scope_object_vector) or scope_object_vector.trigger

Arguments

scope_object_vector
Name of a single scope object, name of a vector of scope objects, list of scope object names in a vector form [scope_object1, scope_object2], or the target object method getscope which returns a scope_object vector.

`scope_object_vector`	Name of a single scope object, name of a vector of scope objects, list of scope object names in a vector form [scope_object1, scope_object2], or the target object method `getscope` which returns a scope_object vector.

Description

Method for a scope object. If the scope object property TriggerMode has a value of 'software', then this function triggers the scope represented by the scope object to acquire the number of data points in the scope object property NumSamples.

Note Only scopes with type host store data in the properties scope_object.Time and scope_object.Data.

Examples

Set a single scope to software trigger, trigger the acquisition or one set of samples, nd plot data.

sc1 = tg.addscope(`host',1) or sc1=addscope(tg,'host',1)
sc1.triggermode = 'software'
tg.start, or start(tg), or +tg
sc1.start  or start(sc1)  or +sc1
sc1.trigger  or trigger(sc1)
plot(sc1.time, sc1.data)
sc1.stop or stop(sc1) or -sc1
tg.stop or stop(tg) or -tg1

Set all scopes to software trigger and trigger to start.

allscopes = tg.getscopes
allscopes.triggermode = 'software'
allscopes.start  or start(allscopes) or +allscopes
allscopes.trigger  or trigger(allscopes)
