Agilent TestExec SL
The Agilent TS-5400 System uses Agilent TestExec SL and system specific software to test the Unit Under Test
(UUT). Agilent TestExec SL is a test executive designed for high-volume, high-throughput functional test
applications. The other system specific software provides the communications between the test executive and
system instruments.
Agilent TestExec SL uses testplans (see “Testplans”) and actions (see “Actions”) to perform the tests. The actions
are the building blocks from which the tests are created. The actions are called from a test which are executed in
a testplan. The switching actions makes the connections from the system instruments, and/or loads on the load
cards to the Unit Under Test. The switching actions are built into Agilent TestExec SL.
Both actions and switching actions are used in a testplan to run the tests. The testplan automatically closes the
appropriate pin matrix and load card switches to make the connections, setup and execute the appropriate sources
and detectors, and return any test results.
The switching information and the instrument types used in the system are located in the system.ust file (see
“System.ust File” on page 11 for more information). This file is generated at the factory and is custom for each
system. It has the necessary information for the switching actions to close the appropriate switches and for the
other actions to communicate with the system instruments. Instrument data in the system.ust file can be generated
and/or modified using the System Configuration Editor (see “System Configuration Editor” on page 13).
