Instrument Reset Management
The Agilent TS-5400 system provides an automatic module/instrument reset
scheme to help ensure that all modules/instruments are placed into a known
safe state before executing a testplan in the event of a problem. The
modules/instruments are configured in the
system.ust file for the reset
operation.
Reset Invocation All instrument reset routines are automatically called when:
• The system is started.
• The Agilent TS-5400 system controller detects an exception (error)
and an error sequence is not defined.
• You insert the predefined global reset action (discussed below) into a
testplan or the error sequence.
If all reset routines execute without raising any exceptions, the system then
resets all registered switching modules (loadcards and pin matrix modules).
Note that a reset function is only registered for instruments with a
sub-instrument number of zero. This is because only a single reset is needed
per instrument, even if the instrument has sub-instruments.
The Agilent TS-5400 system comes with a predefined action called
‘
globalReset’, which you can enter into the error sequence or any test.
This action executes all existing instrument reset routines. The action
definition file, ‘
glbreset.umd’ is located in this directory:
‘
\ProgramFiles\Agilent TestExec SL\actions\handlers’
Refer to the Agilent TestExec SL online help, for more information about
error handling.
Specifying a Reset
Routine
There are two different ways to specify a reset routine in a
module/instrument. One way uses the System Configuration Editor the other
way uses the Agilent TestExec SL Topology Editor. The routine is specified
in the
system.ust file.
The following example shows how to specify the reset routine using the
System Configuration Editor (the recommended method). You can also
enable the reset routine for a module by changing the value of
‘InGlobalReset’ to “1”. Refer to the TestExec SL Online Help for
instructions for the Topology Editor.
Specifying a Reset
Routine Using the
System Configuration
Editor
Run Agilent TestExec SL and load the System Configuration Editor using
the procedure in “Using the System Configuration Editor” on page 55.
Use the procedure in Figure 3-1 to specify a reset routine.
