Section 1 General Information 1.1 Introduction The following paragraphs discuss the overall hardware and software configurations of the system necessary to run the example application programs in this guide. 1.2 Hardware Configuration 1.2.1 System Configuration Figure 1-1 shows the overall hardware configuration of a typical test system. The various components in the system perform a number of functions: Series 2600 System SourceMeter Instruments: System Source­­ Meter instruments are specialized test instruments capable of sourcing current and simultaneously measuring voltage, or sourcing current...

Section 1 General Information on the digital I/O port on the Models 2601 and 2602 System SourceMeter instruments is not suitable for control of safety circuits and should not be used to control a safety interlock. The Interlock pin on the digital I/O port for the Models 2611, 2612, 2635, and 2636 can be used to control a safety interlock. Computer: The test programs in this document require a PC with IEEE-488 (GPIB) communications and cabling. Software: Series 2600 System SourceMeter instruments each use a powerful on-board test sequencer known as the Test Script Processor (TSP™). The TSP is...
