Global timers 1 and 2
In addition to the resource terms available, there are two global timers
available. Each timer can be started, paused, continued, or stopped, from
any sequence level except the first.
Assigning resource term names and values
The Terms field identifies the list of available resource terms within the
analyzer. A resource term can be assigned to only one machine at a time.
The resource term names (a
−
j, Edge1, Edge2, Range1, Range2) are default
names that can be changed. You assign values in the following two ways:
•
Using Preset Values
•
Assigning Bit by Bit

are selected, a configuration pop-up appears. Use this pop-up menu to
quickly set the resource term to a preset value.
Using Preset Values
Assign Assign toggles which machine the term is assigned to. All of the
available resource terms except the Edge terms can be assigned to any
analyzer. However, a term can only be assigned to one analyzer at a time.
