  • Page 77: Structure And Syntax Of The Device Messages

    EB200 Manual Remote control 4.4 Structure and syntax of the device messages 4.4.1 SCPI introduction SCPI (Standard Commands for Programmable Devices) describes a standard command set for programming devices, irrespective of the type of device or manufacturer. The goal of the SCPI consortium is to standardize the device-specific commands to a large extent.

  • Page 78: Fig. 4-1: Tree Structure Of The Scpi Command System Using The Sense System By Way Of An Example

    EB200 Manual Remote control Device-specific commands Hierarchy: Device-specific commands are of hierarchical structure (see Fig. 4-1). The different levels are represented by combined headers. Headers of the highest level (root level) have only one keyword. This keyword denotes a complete command system.

  • Page 79: Remote Control

    EB200 Manual Remote control Some keywords occur at several levels within one command system. Their effect depends on the structure of the command, that is to say, at which position in the header of a command they are inserted. Example: OUTPut:OUTPut:SQUelch:STATe ON This command contains the keyword STATe at the third command level.
  • Page 80 EB200 Manual Remote control Note: The short form is marked by upper-case letters, the long form corresponds to the complete word. Upper-case and lower-case notation only serve the above purpose, the device itself does not make any difference between upper- and lower-case letters.

  • Page 81: Structure Of A Command Line

    EB200 Manual Remote control 4.4.3 Structure of a command line Several commands in a line are separated by a semicolon ";". If the next command belongs to a different command system, the semicolon is followed by a colon. Example: SENSe:FREQuency:STARt MINimum;:OUTPut:FILTer:LPAS:STATe ON This command line contains two commands.

  • Page 82: Responses To Queries

    EB200 Manual Remote control 4.4.4 Responses to queries A query is defined for each setting command unless explicitly specified otherwise. It is formed by adding a question mark to the associated setting command. According to SCPI, the responses to queries are partly subject to stricter rules than in standard IEEE 488.2.

  • Page 83: Parameters

    EB200 Manual Remote control 4.4.5 Parameters Most commands require a parameter to be specified. The parameters must be separated from the header by a "white space". Permissible parameters are numerical values, Boolean parameters, text, character strings, block data and expressions. The type of parameter required for the respective command and the permissible range of values are specified in the command description (see "Description of commands"...
