functions.

functions.

Displaying Scope Object Properties for a Single

Scope

To list the properties of a single scope object, sc1,

1 In the MATLAB window, type

sc1 = getscope(tg,1) or sc1 = tg.getscope(1)

MATLAB creates the scope object sc1 from a previously created scope.

2 Type

sc1

The current scope properties are uploaded to the host PC, and then

MATLAB displays a list of the scope object properties with the updated

values. Because

sc1 is a vector with a single element, you could also type

sc1(1) or sc1([1]).

Note Only scopes with type host store data in the properties

scope_object.Time and scope_object.Data.
