trigger
Purpose Software-trigger start of data acquisition for scope(s)
Syntax MATLAB command line
trigger(scope_object_vector) or scope_object_vector.trigger
Arguments
scope_object_vector
Name of a single scope obje ct, n ame 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 sc ope object. If the scope object property TriggerMode has
avalueof
'software', this function triggers the scope represented by
the scope object to acquire the number of data points in the scope object
property
NumSamples.
Note that only scopes with type
host store data in the properties
scope_object.Time and scope_obj ect.Data.
Examples Set a single scope to software trigger, trigger the acquisition of one set
of samples, and 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 a nd trigger to start.
allscopes = tg.getscopes
