UtilitiesSMIQCalibration LEV PRESETThe vector modulator is aligned in terms of residual carrier, IQ imbalance and quadrature. With optionsSMIQB10/B20 MCOD, SMIQB14/15 FSIM and SMIQB17 NDSIM provided, calibrations are called up forthese modules too and the module offset and partly the IQ imbalance are calibrated. Since thecalibrations are interdependent, calling up individual calibrations is not recommended. All calibrationsare run internally. Calibration should be called up after a warm-up time of approx. 1 h or in case of atemperature change of more than 5°C .Menu selection:UTILITIES - CALIB - LEV PRESETFREQ 100. 000 000 0 MHz LEVEL - 30.0 dBmFREQUENCYLEVELANALOG MODVECTOR MODDIGITAL MODDIGITAL STDLF OUTPUTSWEEPLISTMEM SEQUTILITIESSYSTEMREF OSCPHASEPROTECTCALIBDIAGTESTMOD KEYAUX I/OBEEPERINSTALLALLVCO SUMVECTOR MODLEV PRESETOSC REFLEVELALC TABLELEV ATTCALIBRATETABLE IQMOD-CW IQMOD-VM IQCONVIEW000100020003000400050006300.000 0 kHz +231.000 000 0 MHz +231.000 000 1 MHz +242.000 000 0 MHz +242.000 000 1 MHz +253.000 000 0 MHz +25Fig. 2-264Menu UTILITIES - CALIB - LEV PRESETCALIBRATETriggers the calibration for level preset.IEC/IEEE-bus command :CAL:LPR?The following parameters are only necessary for the indication of the correction values:TABLEVIEWSelection of the correction values displayed by VIEWIQMOD-CW Correction values of module "IQ-Modulator", valid with CWmodeIQMOD-VM Correction values of module "IQ-Modulator", valid with IQmodeCONVERTER Correction values of module "IQ-Converter"The cursor wraps to index 1 of the list.
