Section 8: Keithley User Library Tool (KULT)
LPTLib and KITE interaction via UTMs
ITMs and UTMs are typically independent. However, an ITM and a UTM are not independent if 1)
the UTM occurs before an ITM in the project plan, and 2) the UTM configures a switch matrix.
Under these conditions, the following occur:
•
KITE assumes that the ITM depends on the UTM-created switch configuration.
•
KITE maintains the UTM-created switch configuration during execution of the ITM.
Refer to
Table 8-27

Cross-platform LPTLib compatibility
The LPT Library (LPTLib) is included with the 4200-SCS to provide an application programming
interface (API) for controlling instrumentation and accessing I/O. LPTLib is available on the
Keithley Instruments Models S400 and S600 series parametric test systems for the same purpose.
Therefore, user libraries can be moved between the Keithley Instruments Model 4200-SCS, S400,
and S600 test systems. In most cases, user libraries can be moved from one system to another
with little or no modification to the user library source code. Simply recompile and build the library
on the target platform, and the library is ready for use. However, in some cases it is necessary to
modify the user library to address platform-specific differences in LPTLib functions.

A dash (-) indicates that the corresponding LPTLib function is not supported on the
indicated Keithley Instruments test system.
•
An X indicates that the function is supported on the indicated Keithley Instruments test
system.
•

describes the significant platform differences.
Unless otherwise indicated, unsupported LPTLib functions in
user module. Use of an unsupported function causes a build error of the form:
<module_name>.obj: error LNK2001: unresolved external symbol _<function_name>
Use of an unsupported function may also cause a compilation error of the form:
