Operating Manual R&S SMIQ - Volume 1 - Rohde & Schwarz

SMIQDescription of Commands&GTLGO TO LOCAL: The IEC bus (IEEE488) includes line message REN (remote enable). If thedevice is controlled via a serial interface (RS-232), a remote/local switchover is not possible withthis line. This new command in line with IEEE1174 has been therefore introduced so that thedevice can be switched to local mode via remote control (in the same way as with the front-panelLOCAL key). The device automatically goes to the remote status as soon as the first remotecommand has been received. The command is also of importance when the device is to becontrolled alternately via the IEC/IEEE bus and the serial interface. The device should go to localbefore it can recognize a command from the other interface.*IDN?IDENTIFICATION QUERY queries the instrument identification.The device response is for example: "Rohde&Schwarz, SMIQ03B,00000001, 1.03"03B = variant identification00000001= serial number1.03 = firmware version number*IST?INDIVIDUAL STATUS QUERY returns the contents of the IST flag in decimal form (0 | 1). TheIST flag is the status bit which is sent during a parallel poll (cf. Section 3.6.3.2).*OPCOPERATION COMPLETE sets bit 0 in the event status register when all preceding commandshave been executed. This bit can be used to initiate a service request (cf. Section 3.6).*OPC?OPERATION COMPLETE QUERY returns 1, if all preceding commands have been executed. Itis necessary to consider a sufficiently long time-out for the IEEE/IEC-bus.*OPT?OPTION IDENTIFICATION QUERY queries the options included in the instrument and returns alist of the options installed. The options are separated from each other by means of commas.Table 3-2 List of possible responses to *OPT?ResponseSM-B1SM-B5SMIQB10SMIQB11SMIQB12SMIQB12SMIQB14SMIQB15SMIQB16SMIQB17SMIQB20SMIQB21SMIQB43SMIQB45SMIQB47SMIQB48SMIQB49OptionReference oscillator OCXOFM/PM modulatorModulation coderData generatorMemory extension for SMIQB11Second memory extensionFading simulatorSecond fading simulatorBroadband FMNoise generator/distortion simulatorModulation coderBit error rate testDigital Standard W-CDMADigital Standard 3GPP W-CDMALOW ACP FilterEnhanced Channels for 3GPP W-CDMADynamic FadingExample for a device response:SM-B1,SM-B5,SMIQB10,SMIQB11,SMIQB12,SMIQB12,SMIQB14,SMIQB15,01125.5555.03 3.15E-7
