    Messages SMIQ 3.2.2 Remote Control via RS-232-Interface 3.2.2.1 Setting the Transmission Parameters To enable an error-free and correct data transmission, the parameters of the unit and the controller should have the same setting. To prevent any problems during binary data transmission, the RS-232 interface is set for 8 data bits, no parity and 1 stop bit.

  • Page 33: Device Messages (Commands And Device Responses)

    SMIQ Structure and Syntax of the Device Messages 3.3.2 Device Messages (Commands and Device Responses) Device messages are transferred on the data lines of the IEC bus, the "ATN" control line not being active. ASCII code is used. The device messages are largely identical for the two interfaces (IEC bus and RS232) .

  • Page 34: Structure Of A Command

    Structure and Syntax of the Device Messages SMIQ 3.4.2 Structure of a Command The commands consist of a so-called header and, in most cases, one or more parameters. Header and parameter are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank). The headers may consist of several key words.
  • Page 35 SMIQ Structure and Syntax of the Device Messages 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. Example: SOURce:FM:POLarity NORMal This command contains key word POLarity in the third command level.

  • Page 36: Structure Of A Command Line

    Structure and Syntax of the Device Messages SMIQ 3.4.3 Structure of a Command Line A command line may consist of one or several commands. It is terminated by a <New Line>, a <New Line> with EOI or an EOI together with the last data byte. Quick BASIC automatically produces an EOI together with the last data byte.

  • Page 37: Parameter

    SMIQ Structure and Syntax of the Device Messages 3.4.5 Parameter 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 3.5).
  • Page 38 Structure and Syntax of the Device Messages SMIQ Block data Block data are a transmission format which is suitable for the transmission of large amounts of data. A command using a block data parameter has the following structure: Example: HEADer:HEADer #45168xxxxxxxx ASCII character # introduces the data block.

  • Page 39: Overview Of Syntax Elements

    SMIQ Structure and Syntax of the Device Messages 3.4.6 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 separating semicolon marks the uppermost command level.

  • Page 40: Description Of Commands

    Description of Commands SMIQ Description of Commands 3.5.1 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 41 SMIQ Description of Commands 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 42: Common Commands

    Description of Commands SMIQ 3.5.2 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 an asterisk "*" followed by three letters. Many common commands refer to the status reporting system which is described in detail in Section 3.7.
  • Page 43 SMIQ Description of Commands &GTL GO TO LOCAL: The IEC bus (IEEE488) includes line message REN (remote enable). If the device is controlled via a serial interface (RS-232), a remote/local switchover is not possible with this line. This new command in line with IEEE1174 has been therefore introduced so that the device can be switched to local mode via remote control (in the same way as with the front-panel LOCAL key).
  • Page 44 Description of Commands SMIQ *PRE 0 to 255 PARALLEL POLL REGISTER ENABLE sets the parallel poll enable register to the value indicated. 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 45: Abort System

    SMIQ ABORt System 3.5.3 ABORt System The ABORt system contains the commands to abort actions triggered. After an action has been aborted, it can be triggered again at once. All commands trigger an event, thus they have no *RST value. Further commands for the trigger system of the SMIQ can be found in the TRIGger system.

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

  • Page 244: Command Recognition

    Instrument Model and Command Processing SMIQ 3.6.2 Command Recognition The command recognition analyses the data received from the input unit. It proceeds in the order in which it receives the data. Only a DCL is serviced with priority, a GET (Group Execute Trigger), e.g., is only executed after the commands received before as well.

  • Page 245: Output Unit

    SMIQ Instrument Model and Command Processing 3.6.5 Output Unit The output unit collects the information requested by the controller, which it receives from the data set management. It processes it according to the SCPI rules and makes it available in the output buffer. The output buffer has a size of 1024 characters.
  • Page 246 Status Reporting System SMIQ Status Reporting System The status reporting system (cf. Fig. 3-4) stores all information on the present operating state of the instrument, e.g. that the instrument presently carries out an AUTORANGE and on errors which have occurred. This information is stored in the status registers and in the error queue. The status registers and the error queue can be queried via IEC bus.
  • Page 247 SMIQ Status Reporting System 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.

    SMIQ Status Reporting System 3.7.3 Description of the Status Registers 3.7.3.1 Status Byte (STB) and Service Request Enable Register (SRE) The STB is already defined in IEEE 488.2. 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.

    Status Reporting System SMIQ 3.7.3.2 IST Flag and Parallel Poll Enable Register (PPE) By analogy with the SRQ, the IST flag combines the entire status information in a single bit. It can be queried by means of a parallel poll or using command "*IST?". The parallel poll enable register (PPE) determines which bits of the STB contribute to the IST flag.

  • Page 253 SMIQ Status Reporting System 3.7.4 Application of the Status Reporting Systems In order to be able to effectively use the status reporting system, the information contained there must be transmitted to the controller and further processed there. There are several methods which are represented in the following.
  • Page 254 Status Reporting System SMIQ 3.7.4.3 Parallel Poll In a parallel poll, up to eight instruments are simultaneously requested by the controller by means of a single command to transmit 1 bit of information each on the data lines, i.e., to set the data line allocated to each instrument to logically "0"...

  • Page 256 Fast Restore Mode SMIQ Fast Restore Mode Device settings can be saved and recalled very quickly via the IEC/IEEE bus using the commands described below. 1000 memory locations are available. In contrast to the SAVE/RECALL function, not the unit parameters but only the setting data of the modules are stored in the Fast Restore mode.
