You can use remote control over thegeneral-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 functionslike any other GPIB instrument.This section contains:• KXCI user interface: Describes how to use the KXCI user interface, which is used to control GPIBoperation.• GPIB command set: The command strings to control the source-measure operations of the4200A-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 Ethernetcommunications.• 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 tothe computer for both system mode and user mode.Section 9Keithley External Control Interface (KXCI)
