This includes the description of the command structure and syntax according to the SCPI standard, the description of command execution and of the status registers.
Page 164: Getting Started
Getting Started R&S SMB Note: Manual control is designed for maximum possible operating convenience. In contrast, the priority of remote control is the "predictability" of the device status. Therefore, control programs should always define an initial device status (e.g. with the command *RST) and then implement the required settings.
Page 165: Remote Control Via Iec/Ieee Bus
R&S SMB Switchover to Remote Control The instrument remains in the REMOTE mode until local control is selected either manually with the key on the front panel or with the interface command &GTL via the remote-control interface. LOCAL Switching from manual operation to remote control and vice versa does not affect the remaining instrument settings.
Page 166: Remote Control Via Lan Interface
Switchover to Remote Control R&S SMB Remote Control via LAN Interface For remote control via a network, the PC and the instrument must be connected via the LAN interface to a common network with TCP/IP network protocol. Connection of the Signal Generator to a network and the querying of a computer name is described in section "Connection to the Network".

R&S SMB SCPI Command Structure and Syntax Structure of a Command Line A command line may consist of one or several commands. It is terminated by an EOI together with the last data byte. Several commands in a command line must be separated by a semicolon ";". If the next command belongs to a different command system, the semicolon is followed by a colon.
Page 176: Responses To Queries
SCPI Command Structure and Syntax R&S SMB 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 177: Parameters
R&S SMB SCPI Command Structure and Syntax 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.

The individual components work independently and simultaneously. They communicate with each other by means of so-called "messages".
Page 181: Command Recognition
R&S SMB Instrument Model and Command Processing 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.
Page 182: Status Reporting System
Instrument Model and Command Processing R&S SMB The command for setting the FM deviation is rejected and an execution error is generated. At the time when this command is processed, the previous setting of the RF frequency (60 MHz) is still valid, i.e. the value for the FM deviation is outside the permissible value range. The two other commands are set.
Page 183 R&S SMB Instrument Model and Command Processing If a particular device action can be performed only after the execution of a previous overlapped command, the controller must know when the overlapped command has finished. The necessary interaction between the controller and the test instrument is called command synchronization. Command Sequence According to section "Database and Instrument...
Page 184 Instrument Model and Command Processing R&S SMB Command synchronization by means of a *WAI or *OPC? appended to an overlapped command is a good choice if the overlapped command takes only little time to process. The two synchronization techniques simply block overlapped execution of the command. For time consuming overlapped commands it is usually desirable to allow the controller or the R&S signal generator to do other useful work while waiting for command execution.
Page 185: Status Reporting System
R&S SMB Status Reporting System Status Reporting System The status reporting system stores information on errors which have occurred. This information is stored in theerror queue. The error queue can be queried via IEC/IEEE bus or via the Ethernet. The information is of a hierarchical structure. The register status byte (STB) defined in IEEE 488.2 and its associated mask register service request enable (SRE) form the uppermost level.

Page 188: Application Of The Status Reporting System
Status Reporting System R&S SMB Application of the Status Reporting System In order to effectively use the status reporting system, the information contained there must be transmitted to the controller and further processed. There are several methods, which are outlined in the following.
Page 189 R&S SMB Status Reporting System The instrument first has to be set for the parallel poll using the VISUAL BASIC command "IBPPC()". This command allocates a data line to the instrument and determines whether the response is to be inverted. The parallel poll itself is executed using "IBRPP()". The parallel poll method is mainly used to find out quickly which one of the instruments connected to the IEC/IEEE bus has sent a service request.

Hardware Interfaces R&S SMB Hardware Interfaces The following section describes the remote-control interfaces of the signal generator. All other interfaces are described in Chapter 1, sections "Legend for Front Panel View" and "Legend for Rear Panel View". For specifications refer to the data sheet. IEC/IEEE Bus Interface The standard instrument is equipped with an IEC/IEEE bus connector.
Page 301 R&S SMB Hardware Interfaces 2. Control bus with 5 lines IFC (Interface Clear) active LOW resets the interfaces of the instruments connected to the default setting. ATN (Attention) active LOW signals the transmission of interface messages. inactive HIGH signals the transmission of device messages. SRQ (Service Request) active LOW enables the connected device to send a service request to the controller.
Page 302 Hardware Interfaces R&S SMB IEC/IEEE Bus Messages Interface messages are transferred on the data lines of the IEC/IEEE bus when the "ATN" control line is active (LOW). They are used for communication between controller and instruments and can only be sent by the controller which currently has control of the IEC/IEEE bus.
Page 303: Lan Connector
R&S SMB Hardware Interfaces LAN Connector The unit is equipped with an LAN interface as standard. The LAN connector is at the rear of the instrument. Provided the appropriate rights have been assigned by the network administrator, files can be transmitted via the network, and network resources, e.g. a network folders, can be used. The instrument can also be remote-controlled and manually operated in the network.
Page 304 Hardware Interfaces R&S SMB Core channel (program, response, control messages ) Controller Instrument Abort channel (abort) Interrupt channel (Service request) Fig. 8-3 VXI-11 channels between instrument and controller The number of controllers that can address an instrument is practically unlimited in the network. In the instrument, the individual controllers are clearly distinguished.
Page 305 R&S SMB Hardware Interfaces VXI-11 Interface Messages On the Ethernet link, the interface messages are called low-level control messages. These messages can be used to emulate interface messages of the IEC/IEEE bus.

R&S SMB Introduction - Status Information and Messages 9 Error Messages Introduction - Status Information and Messages This chapter describes the error messages of the signal generator. The error messages are output in the Info line on the screen and entered in the error error/event queue of the status reporting system. A great variety of different messages such as status messages, error messages, warnings or information are displayed in the header field of the screen.
Page 310 Status Information R&S SMB LEVEL OFFSET A level offset is set. The level entered and displayed in the Level field takes the offset of any downstream attenuators/amplifiers into consideration by way of calculation. This means that with a level offset the level displayed in the header does not correspond to the level at the RF output, but rather to the level at the output of the downstream instrument.
