Figure A-30 shows a solution for the first step of using the
Sequencer.
Figure A-30. Using the Sequencer, Step 1
Key Points
n Setting Global Variables with a UserFunction: A typical use of the
first
Sequencer transaction is to call a UserFunction that sets the
Global Variables, as it does in this case. Then you can utilize these
variables in any test that follows, as is shown here.
n The Sequencer Return Pin: The
Return pin in this example delivers a
PASS or FAIL message plus the test value. You could use this pin to
deliver any message or value from a particular test.
