MTS Multipurpose Elite - Manual (Page 486)

Presentation of non-cycle data variables requires that the variables are used in the test definition and the
variables are selected for presentation in the runtime user interface.
Scopes
About Scopes
A scope is a time-based chart, similar in principle to an oscilloscope, that you can use to plot data over a
specified period of time. A scope can plot one or more trace signals on the Y axis and either time or another
trace signal on the X axis. Additional trace signals can be added to additional Y axes.
You can set up and use signal scopes in two ways: for general system operation or for within a test. A
difference in these uses of a scope depends on where the scope is opened.
Scope through Display menu
A scope created through the Display menu is used for general system operations. A scope used for general
system operation must be configured using numeric and signal values. Variables are not available because
variables are part of the test definition and the scope runs outside the test environment.
Scope through monitor display
A scope added to a Monitor Display monitors signals or variable values during a test run.
Runtime signal scopes can be configured using variables because they reside within the test environment.
Signal scopes are cycle based. Other cyclic views are the Cycle Time, History and Hysteresis charts.
Variable value scopes monitor the current value of a variable during test execution. Other variable-based
views are the Time Array Data Table and the Array-Variable Chart.

Scope for General System Operation
This type of scope can be used any time the application receives signal data from the test station. The
Configure Chart and Run Scope buttons are disabled when the application is disconnected from a test
station.
When you create a scope from the Display menu:
• The scope shows signals for general system operations. You are not required to create a test to set
up and run the scope.
• The scope updates continually when connected to a test station and shows the actual signal status,
regardless of the state of the test.
