3 Signature of a Testlet
3.1 Introduction
Each testlet has a signature which consists of stimulation, observation and local channels.
Channels may be assigned using the “signature” tab from the main window. The currently
selected testlet is represented by a grey rectangle and channels are displayed as arrow-headed
lines. Stimulation channels are shown on the right of the testlet and observation channels on
the left, local channels are shown within the testlet rectangle (see Figure 4).
The following sections describe how to create or alter the signature of a testlet.
3.2 Assigning observation channels
Figure 4: The testlet signature
A new observation channel may be added to a testlet’s signature by moving the mouse over
the area to the left of the testlet and clicking the left mouse button. A pop-up window appears
which contains two list boxes, one on the left and one on the right side of the dialog box. The
list on the left side shows all channels that are known to the system, but are not yet assigned to
the current testlet’s signature (see Figure 5). If there are no channels that might be assigned to
the testlet, this list will be empty.
If channels are available they can be added to, or removed from the set of observation channels
on the right hand side.
