1. CSW Series CSW Series SCPI Programming Manual AMETEK Programmable Power 2 Introduction to SCPI SCPI Standard Commands for Programmable Instruments is a programming language for controlling instrument functions over the IEEE 488 SCPI is layered on top of the hardware portion of IEEE 488 1 The same SCPI commands and parameters control the same functions in different classes of instruments For example you would use the same MEAS VOLT command to measure the AC DC source output voltage or the output voltage measured using a SCPI compatible multimeter 2 1 Conventions Used in This Manual Angle brackets lt gt Items within angle brackets are parameter abbreviations For example lt NR1 gt indicates a specific form of numerical data Vertical bar Vertical bars separate alternative parameters For example FIX STEP indicates that either FIX or STEP can be used as a parameter Square Brackets Items within square brackets are optional The representation SOURce LIST means that SOURce may be omitted Braces Braces indicate parameters that may be repeated zero or more times It is used especially for showing arrays The notation lt A gt lt B gt shows that parameter A must be entered while parameter B may be omitted or may be entered one or more times Boldface font Boldface font is used to emphasize syntax in command definitions TRIGger SOURCe lt NRf gt shows a command definition Computer font Com
