Page 167: Description Of Status Registers
R&S®SML / R&S®SMV03 Status Reporting System Description of Status Registers 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.
Page 168: Table 5-3 Meaning Of The Bits Used In The Event Status Register
Status Reporting System R&S®SML / R&S®SMV03 IST Flag and Parallel Poll Enable Register (PPE) Analogously 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 (see section "Parallel Poll") or using the command *IST?. The parallel poll enable (PPE) register determines which bits of the STB contribute to the IST flag.

Page 170: Use Of Status Reporting System
Status Reporting System R&S®SML / R&S®SMV03 Use of Status Reporting System To make effective use of the status reporting system, the information collected there must be transferred to the controller and further processed. There are several methods to this effect which are described in the following.
Page 171 R&S®SML / R&S®SMV03 Status Reporting System 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, ie to set the data line allocated to each instrument to logically "0"...
Page 172: Reset Values Of Status Reporting System
Status Reporting System R&S®SML / R&S®SMV03 Reset Values of Status Reporting System Table 5-4 lists the commands and events that cause a reset of the status reporting system. Except for *RST and SYSTem:PRESet, none of the commands has an effect on the functional settings of the instrument.
Page 173: Interfaces
R&S®SML / R&S®SMV03 Interfaces Interfaces IEC/IEEE-Bus Interface The instrument is equipped with an IEC/IEEE-bus interface as standard. The connector to IEEE 488 is provided at the rear of the instrument. A controller for remote control can be connected via the interface. Connection is made using a shielded cable.
Page 174 Interfaces R&S®SML / R&S®SMV03 2. Control bus with 5 lines (Interface Clear): Active LOW resets the interfaces of the instruments connected to the default setting. (Attention): Active LOW signals the transmission of interface messages. Inactive HIGH signals the transmission of device messages. SRQ (Service Request): Active LOW enables the instrument to send a service request to the controller.
Page 175 R&S®SML / R&S®SMV03 Interfaces Interface Messages Interface messages are transmitted to the instrument on the data lines, with the ATN (Attention) line being active LOW. These messages serve for communication between the controller and the instrument. Universal Commands Universal commands are in the code range 10 to 1F hex. They act on all instruments connected to the bus without addressing them before.
Page 176: Rs-232-C Interface
Interfaces R&S®SML / R&S®SMV03 RS-232-C Interface The instrument is fitted with an RS-232-C interface as standard. The 9-contact interface is provided at the rear of the unit. A controller for remote control can be connected via the interface. Characteristics of Interface Serial data transmission in asynchronous mode Bidirectional data transmission via two separate lines Selectable transmission rate from 120 to 15200 baud...
Page 177 R&S®SML / R&S®SMV03 Interfaces Transmission Parameters To ensure error-free and correct data transmission, the transmission parameters on the instrument and the controller must have the same settings. The settings are made in the Utilities - System-RS232 menu. Transmission rate Eight different baud rates can be set on the instrument: (baud rate) 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 Data bits...
Page 178 Interfaces R&S®SML / R&S®SMV03 Handshake Software handshake The software handshake with the XON/XOFF protocol controls data transmission. If the receiver (instrument) wishes to inhibit the input of data, it sends XOFF to the transmitter. The transmitter then interrupts data output until it receives XON from the receiver. The same function is also provided at the transmitter end (controller).
Page 179: Remote Control - Description Of Commands
R&S®SML / R&S®SMV03 Description of Commands 6 Remote Control – Description of Commands 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 180 Description of Commands R&S®SML / R&S®SMV03 Upper/lower case Upper/lower case letters serve to mark the long or short form of the key notation words of a command in the description. The instrument itself does not distinguish between upper and lower case letters. Special characters A selection of key words with an identical effect exists for several commands.
Page 181: Common Commands
R&S®SML / R&S®SMV03 Common Commands 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 Chapter 5.
Page 182: Table 6-2 Device Response To *Opt
Common Commands R&S®SML / R&S®SMV03 *IDN? IDENTIFICATION QUERY queries the instrument identification. The device response is for example: "Rohde&Schwarz,R&S SML01,00000001,1.04" 01 = variant identification 00000001= serial number 1.04 = firmware version number *IST? INDIVIDUAL STATUS QUERY returns the contents of the IST flag in decimal form (0 | 1). The IST flag is the status bit which is sent during a parallel poll.
Page 183 R&S®SML / R&S®SMV03 Common Commands *RCL 1 to 50 RECALL calls the instrument state which was stored under the number supplied using command *SAV. 50 instrument states can be stored. *RST RESET sets the instrument to a defined default status. The command essentially corresponds to pressing the [PRESET] key.
Page 184: Abort System
ABORt / CALibration R&S®SML / R&S®SMV03 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 R&S SML / R&S SMV03 can be found in the TRIGger system.
Page 185 R&S®SML / R&S®SMV03 CALibration :CALibration:ATTenuator:STATe The command switches ON or OFF the correction values of the attenuator. Example: *RST value is ON :CAL:ATT:STAT :CALibration:LPReset[:MEASure]? The command calibrates Level Preset. "0" is returned for O.K. and "1" in case of an error. Example: :CAL:LPR? :CALibration:LFGenlevel[:MEASure]?
Page 186: Diagnostic System
DIAGnostic R&S®SML / R&S®SMV03 DIAGnostic System The DIAGnostic system contains the commands for diagnostic test and service of the instrument. SCPI does not define DIAGnostic commands, the commands listed here are R&S SML / R&S SMV03-specific. All DIAGnostic commands are queries which are not influenced by *RST. Hence no default setting values are stated.
Page 187 R&S®SML / R&S®SMV03 DIAGnostic :DIAGnostic:INFO:SDATe? The command queries the date of software creation. The response is returned in the form year, month, day. Example: Response: 1999, 12, 19 :DIAG:INFO:SDAT? :DIAGnostic:[:MEASure] The commands which trigger a measurement in the instrument and return the measured value are under this node.

R&S®SML / R&S®SMV03 Maintenance Maintenance The present chapter describes the measures that are necessary for maintaining, storing and packing the instrument. The instrument does not need a periodic maintenance. What is necessary is essentially the cleaning of the outside of the instrument. However, it is recommended to check the rated data from time to time.
