Fading SimulationSMIQINSERTION LOSSSETTING MODESET DEFAULTPATHPROFILEFREQ RATIOSelection of a setting mode for the insertion loss of the fading simulator.See explanation under STANDARD FADING.IEC/IEEE-bus command :SOUR:FSIM:BIRT:ILOS:MODE NORM:SOUR:FSIM:BIRT:ILOS:MODE LACPSets the default setting of the path parameters.IEC/IEEE-bus command :SOUR:FSIM:BIRT:DEFIndicates the paths for subsequent parameters. These parameters can be setindividually for each path.Selection of a fading profile. Only pDOPP is available here; when FREQRATIO = 0 is set a "non-fading“ path is obtained.pDOPP (pure DOPPler) Simulation of a transmission path having a singledirect connection from the transmitter to the moving receiver(discrete component).The Doppler frequency shift is determined by the parametersDOPPLER FREQ and FREQ RATIO.IEC/IEEE-bus command :SOUR:FSIM:BIRT:PATH1:PROF PDOPEntry value of ratio of actual Doppler frequency shift. See explanation underSTANDARD FADING. When FREQ RATIO = 0 is set, a "non-fading" path isobtained.IEC/IEEE-bus command :SOUR:FSIM:BIRT:PATH1:FRAT 1SPEED Entry value of the speed v of the moving receiver.See explanations under STANDARD FADING.All entries in path 1 are copied for path 2.IEC/IEEE-bus command :SOUR:FSIM:BIRT:PATH1:SPE 100DOPPLER FREQPATH LOSSEntry value of the magnitude of the maximum Doppler frequency shift. Seeexplanation under STANDARD FADING.All entries in path 1 are copied for path 2.IEC/IEEE-bus command :SOUR:FSIM:BIRT:PATH1:FDOP 92.3Entry value of attenuation in path. Value range: 0.0 to 50.0 dB.IEC/IEEE-bus command :SOUR:FSIM:BIRT:PATH2:LOSS 3DELAY Entry value of signal delay in path 1.
