54 Customizing the System Chapter 3
Customizing the Agilent TestExec SL Software to
Accommodate Additional Instrumentation
Each added instrument or altered configuration will require some or all of
the following files to be written or modified:
1. A modified ‘SYSTEM.UST’ file. See “Modifying the system.ust File”
on page 55 for details.
2. An instrument handler routine. Each instrument type requires a piece
of software called an instrument handler be written for it so the
instrument can communicate with the Agilent TS-5400 system.
You will have to write handlers for these additional devices. The
handlers written for Lab Windows, National Instrument’s Labview,
and Agilent VEE do not work with this system. With the new handlers,
you will be able to send and receive messages and data to the added
devices.
“Instrument Handlers” on page 59 explains how to write custom
handlers for new instrumentation.If the additional instrumentation is
the same kind as what is already in the system, then no additional
handler routines need to be written.
3. Modify the system topology file. Use the Switch Configuration Editor
to add the new instrumentation to the system topology file,
‘
SYSTEM.UST’. See “Modifying the system.ust File” on page 55 for
specifics.
Installing Optional
Switching Modules
Using another vendor's switching module will require incorporating the
product information in the appropriate software files: System configuration
file, switch handler routines, and the system topology files.
