Noise Generator and Distortion SimulatorSMIQ(POLYNOMIAL...) INVERSE FUNCTIONLEVEL CORRECTIONCompensation of an amplifier connected after theSMIQ, the coefficients entered correspond to themeasured distortion of the amplifier.OFFONThe above equations are applicable.AM-AM distortion:inverse function of Aout_n (Ain),AM-PM distortion:Pout = Pin - k2*Aout_n(Ain)^1 -k3*Aout_n(Ain)^2 - k4*Aout_n(Ain)^3 -k5*Aout_n(Ain)^4IEEE-bus :SOUR:DIST:POLY:IFUN ONEntry of the level correction for the polynomial. Thevalue entered is active and is displayed in the mainmenu after selection of the polynomial and calling upRECALCULATE. It can be edited only here.Value range: -20 dB to +6 dBIEEE-bus :SOUR:DIST:POLY:LEV:CORR -10 DBLEVEL CORRECTIONRECALCULATEDisplay of level correction to correct the output level so that the attenuation orgain of the distortion simulator can be compensated. For the polynomial thelevel correction can be entered into submenu POLYNOMIAL. The levelcorrection for the lists can only be transferred via the IEC/IEEE bus.Value range: -20 dB to +6 dBIEC/IEEE-bus command :SOUR:DIST:DATA:LEV:CORR -3.12 DBDistortion data are active since as they are transferred into the module. This isnecessary when the available characteristic has been overwritten via theIEC/IEEE bus or when a polynomial parameter has been modified.IEC/IEEE-bus command :SOUR:DIST:REC1125.5555.03 2.386 E-9
