4200A-SCS Parameter Analyzer

Furnished Software Modules

Clarius

The graphical user interface for testing and characterizing your devices, materials and processes. Clarius

software provides a unified measurement interface that guides you through complex characterization

tests, enabling you to focus on your research or development projects.

Keithley User Library Tool (KULT) Assists test engineers to create custom test routines as well as use existing Keithley and third-party

C-language subroutine libraries. Users can edit and compile subroutines, then integrate libraries of

subroutines with Clarius, allowing the 4200A-SCS to control an entire test rack from a single user interface.

Requires optional 4200-Compiler.

Keithley External Control Interface (KXCI)

Controls the 4200A-SCS from an external computer via GPIB bus or Ethernet.

Keithley Configuration Utility (KCon)

Allows test engineers to define the configuration of GPIB instruments, switch matrices, and analytical

probers connected to the 4200A-SCS. It also provides diagnostic functions.

KPulse

A graphical user interface that is a non-programming alternative to configure and control the installed

4225-PMU or 4220-PGU pulse generator modules. It is used for quick tests requiring minimal interaction

with other 4200A-SCS test resources.

Clarius User Interface Software

Clarius is the resident user interface software running on the 4200A-SCS. Clarius runs on the

embedded Windows 7 operating system. It provides test plan selection and development, advanced

test configurations, parameter analysis and graphing, and automation capabilities required for modern

semiconductor device, materials and process characterization.

Data Analysis

Two methods of parameter extraction are available. The Formulator executes data transformations for

performing automated line fits and parameter extraction. A spreadsheet offers standard spreadsheet

analysis tools. Many of the sample libraries include parameter extraction examples.

Formulator

The Formulator supports mathematical functions, conversion functions, search functions, common industry

constants and line fit/parameter extraction functions. The Formulator supports the following functions:

index position (AT), average (AVG), moving average (MAVG), conditional computation (COND), derivative

(DELTA), differential coefficient (DIFF), exponential (EXP), square root (SQRT), natural logarithm (LN),

logarithm (LOG), integral (INTEG), standard deviation (STDEV), moving summation (SUMMV), arc cosine
