UtilitiesSMIQ2.29.5 Indication of the IEC-Bus Language (LANGUAGE)Submenu UTILITIES-SYSTEM LANGUAGE indicates the IEC-bus language and the current SCPIversion.2.29.6 Reference Frequency Internal/External (REF OSC)In the internal-reference operating mode, the internal reference signal at a frequency of 10 MHz isavailable at the REF socket (rear of the instrument).Signal level: V eff (EMF, sine) = 1 V.The frequency of the internal reference oscillator can be detuned via the EXT TUNE input (rear of theinstrument). Input voltage range ±10 V, pulling range ±1×10 -6 .The external detuning is possible in both states of the ADJUSTMENT STATE (ON or OFF) unlessoption SM-B1, reference oscillator OCXO, is fitted. If option SM-B1, reference oscillator OCXO, is fitted,the detuning via the TUNE input is only possible if the ADJUSTMENT STATE selection has beenswitched to ON in the UTILITIES-REF OSC menu.In the external-reference operating mode, an external signal at a frequency of 1 MHz to 16 MHz(spacing 1 MHz) is to be fed into socket REF. The setting to external frequency is effected in theUTILITIES-REF OSC menu.Signal level:V eff = 0.1 to 2 VThe message "EXT REF" is displayed in the status line in the header field of the display in theexternal-reference operating mode.Menu selection:UTILITIES - REF OSCFREQ100. 000 000 0 MHz LEVEL - 30.0 dBmFREQUENCYLEVELANALOG MODVECTOR MODDIGITAL MODDIGITAL STDLF OUTPUTSWEEPLISTMEM SEQUTILITIESSYSTEMREF OSCPHASEPROTECTCALIBDIAGTESTMOD KEYAUX I/OBEEPERINSTALLSOURCEEXT FREQUENCYADJUSTMENT STATEFREQUENCY ADJUSTMENTINTEXT10 MHzOFF ON2048Fig. 2-258SOURCEMenu UTILITIES - REF OSC (preset setting)Selection of the operating mode.INT Internal-reference operating modeEXT External-reference operating modeIEC/IEEE-bus command SOUR:ROSC:SOUR INT1125.5555.03 2.414E-9
