    CTS30 Remote Control Remote Control Introduction The instrument is equipped with a serial interface (RS 232-C). The connector is located at the rear of the instrument and permits to connect a controller for remote control. The instrument supports the SCPI version 1992.0 (Standard Commands for Programmable Instruments).

  • Page 30: Switchover To Remote Control

    Remote Control CTS30 Switchover to Remote Control On power-on, the instrument is always in the manual operating state ("LOCAL" state) and can be operated via the front panel. It is switched to remote control ("REMOTE" state) as soon as it receives a command from a controller.

  • Page 31: Structure And Syntax Of The Device Messages

    CTS30 Remote Control Structure and Syntax of the Device Messages 3.5.1 SCPI Introduction SCPI (Standard Commands for Programmable Instruments) describes a standard command set for programming instruments, irrespective of the type of instrument or manufacturer. The goal of the SCPI consortium is to standardize the device-specific commands to a large extent.
  • Page 32 Remote Control CTS30 SOURce POWer POLarity MODE EXTernal STATe INTernal POLarity COUPling Fig. 3-1 Tree structure of the SCPI command systems using the SOURce system by way of example Some key words occur in 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.

  • Page 33: Structure Of A Command Line

    CTS30 Remote Control Long and short form: The key words feature a long form and a short form. Either the short form or the long form can be entered, other abbreviations are not permissible. Example: STATus:QUEStionable:ENABle 1= STAT:QUES:ENAB 1 Note: The short form is marked by upper-case letters, the long form corresponds to the complete word.
  • Page 34 Remote Control CTS30 Example: SOURce:FM:MODE LOCKed;:SOURce:FM:INT:FREQuency 1kHz " " This command line is represented in its full length and contains two commands separated from each other by the semicolon. Both commands are part of the SOURce command system, subsystem FM, i.e. they have two common levels.

  • Page 35: Responses To Queries

    CTS30 Remote Control 3.5.4 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 36: Parameters

    Remote Control CTS30 3.5.5 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 and block data. The type of parameter required for the respective command and the permissible range of values are specified in the command description (see Section 3.6).
  • Page 37 CTS30 Remote Control Text Text parameters observe the syntactic rules for key words, i.e. they can be entered using a short or long form. Like any parameter, they have to be separated from the header by a white space. In the case of a query, the short form of the text is provided.

  • Page 38: Overview Of Syntax Elements

    Remote Control CTS30 3.5.6 Overview of Syntax Elements The following survey offers an overview of the syntax elements. The colon separates the key words of a command. In a command line the colon after the separating semicolon marks the uppermost command level.

  • Page 39: Description Of Commands

    CTS30 Remote Control Description of Commands 3.6.1 Notation In the following sections, all commands implemented in the instrument are first listed in tables and then described in detail, separated according to the command system. The notation corresponds to the one of the SCPI standards to a large extent.
  • Page 40 Remote Control CTS30 Special characters A selection of key words with an identical effect exists for several commands. These key words are indicated in the same line, they are separated by a vertical stroke. Only one of these key words has to be indicated in the header of the command.

  • Page 41: Common Commands

    CTS30 Remote Control 3.6.2 Common Commands The common commands are taken from the IEEE 488.2 (IEC 625-2) standard. Same commands have the same effect on different devices. The headers of these commands consist of "*" followed by three letters. Many common commands refer to the status reporting system which is described in detail in Section 3.8.
  • Page 42 Remote Control CTS30 *IDN? IDENTIFICATION QUERY queries the instrument identification. The device response is for example: ROHDE&SCHWARZ,CTSzz,ssssss/sss,x.xx yy.yy.yy (zz is the model no., eg 55 or 65 ssssss/sss is the serial no., eg 101183/005 x.xx is the software version, eg V 1.00 yy.yy.yy is the date, eg 18.10.93)

Query *PRE? returns the contents of the parallel poll enable register in decimal form. *PSC 0 | 1 POWER ON STATUS CLEAR determines whether the contents of the ENABle registers is maintained or reset in switching on.

  • Page 44: Instrument Model And Command Processing

    Remote Control CTS30 Instrument Model and Command Processing The instrument model shown in Fig. 3-2 has been made viewed from the standpoint of the servicing of remote-control commands. The individual components work independently of each other and simultaneously. They communicate by means of so-called "messages".

  • Page 45: Status Reporting System

    CTS30 Remote Control Status Reporting System The status reporting system (cf. Fig. 3-4) stores all information on the present operating state of the instrument and on errors which have occurred. This information is stored in the status registers and in the error queue.
  • Page 46 Remote Control CTS30 CONDition part The CONDition part is directly written into by the hardware or the sum bit of the next lower register. Its contents reflects the current instrument status. This register part can only be read, but not written into or cleared. Its contents is not affected by reading.

It provides a rough overview of the instrument status by collecting the pieces of information of the lower registers. It can thus be compared with the CONDition part of an SCPI register and assumes the highest level within the SCPI hierarchy.
