Introduction
The Keithley External Control Interface (KXCI) allows you to use an external computer to remotely
control the SMUs and pulse generator cards in the 4200A-SCS. You can use remote control over the
general-purpose instrument bus (GPIB) or ethernet. You define the type of communications in KCon
(in the KXCI Settings options). When controlled by an external computer, the 4200A-SCS functions
like any other GPIB instrument.
This section contains:
• KXCI user interface: Describes how to use the KXCI user interface, which is used to control GPIB
operation.
• GPIB command set: The command strings to control the source-measure operations of the
4200A-SCS are summarized in three tables.
• GPIB command reference: Provides detailed reference information on the command set.
• Ethernet command reference: Describes the command set that can be used for Ethernet
communications.
• SMU default settings: Describes how to return the SMUs to their power-on default settings.
Includes a table that lists the default settings.
• Output data formats: Describes the format of the data string that returns measured readings to
the computer for both system mode and user mode.
