SOURce:DM SubsystemSMIQ[:SOURce]:DM:IQ:FILTerThe commands for the IQ filter settings are under this node.[:SOURce]:DM:IQ:FILTer:STATe ON | OFFThis command switches the IQ filter ON or OFF. It is only available with option SMIQB47 - LOWACP Filter.Example: :SOUR:DM:IQ:FILT:STAT ON *RST value: OFF[:SOURce]:DM:IQ:FILTer:FREQuency 850 kHz, 2.5 MHz, 5 MHz, 7.5 MHzThis command selects an IQ filter with the limit frequencies 850 kHz, 2.5 MHz, or 5 MHz or7.5 MHz. It is only available with option SMIQB47 - LOW ACP Filter.Example: :SOUR:DM:IQ:FILT:FREQ 2.5MHZ *RST value is 2.5 MHz[:SOURce]:DM:IQ:TRANsition NORMal | FASTThe command switches over the setting time for the IQ filter. FAST should only be used if a fastswitchover between CW and I/Q modulation is required.Example: :SOUR:DM:IQ:TRAN FAST *RST value is NORM[:SOURce]:DM:LEAKage[:MAGNitude] 0 to 50.0 PCTThis command adjusts the residual carrier amplitude for I/Q modulation.Example: :SOUR:DM:LEAK 3PCT *RST value: 0[:SOURce]:DM:QUADrature:ANGLe -10.0 to 10.0 degreeThis command changes the quadrature offset for I/Q modulation.Example: :SOUR:DM:QUAD:ANGL -5DEG *RST value: 0[:SOURce]:DM:IQRatio[:MAGNitude] -12.0 to 12.0 PCTThis command adjusts the ratio of I and Q modulation (gain imbalance).Example: :SOUR:DM:IQR 4PCT *RST value: 0[:SOURce]:DM:IQSWap[:STATe] ON | OFFThis command interchanges the I and Q channels in position ON.Example: :SOUR:DM:IQSW OFF *RST value: OFF1125.5555.03 3.66E-9
