However, they include a basic delay of 25 nsof the Fading Simulator.- All test cases requiring more than 2 paths are only possible with optionSMIQB15.Selection of the unit required for the speed of parameter SPEED.IEC/IEEE-bus command :SOUR:FSIM:FDEL:SPE:UNIT KMPHSets the default setting of the path parameters with path 1 switched on and allother paths switched off.IEC/IEEE-bus command :SOUR:FSIM:FDEL:DEFIndicates the paths for subsequent parameters. These parameters can be setindividually for each path.Switch-on/off of a path. If the cursor is placed onto a path, this path may beswitched on or off by pressing one of the unit keys (toggle function).IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:STAT ON | OFFSelection of a fading profile. See explanations under Standard Fading. Onlythe following setting is possible:pDOPPIEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:PROF PDOPRAYL (This setting is provided in the 3GPP test cases)IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:PROF RAYLEntry value of the ratio of the actual Doppler frequency shift to the set Dopplerfrequency with FDOP fading switched on. (See explanation under StandardFading).IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:FRAT 1Entry value of the speed v of the moving receiver (see explanation underStandard Fading).IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:SPE 100Entry value of the magnitude of the maximum Doppler frequency shift (seeexplanation under Standard Fading).IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:FDOP 92.3Entry value of attenuation in path.Value range: 0.0 to 50.0 dB.IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:LOSS 3Entry value of signal delay in path.Value range: 25 ns to 1637 µs.IEC/IEEE-bus command :SOUR:FSIM:FDEL:PATH2:DEL 14.5E-61125.5555.03 2.80 E-9
