Fading SimulationSMIQ2.9.4.2 Menu FINE DELAYWith the FINE DELAY mode a better time delay resolution of the paths is obtained. Two paths arepossible for each option (SMIQB14 / SMIQB15). The system bandwidth of these paths is limited to 4.6MHz, which is sufficient for 3GPP with 3.84 Msymb/s. Time resolution is 1 ns.Fig. 2-41Menu FINE DELAYSTATEIGNORE RFCHANGES < 5%STANDARDActivating/deactivating fine delay simulation.IEC/IEEE-bus command :SOUR:FSIM:FDEL:STAT ON | OFFWhen switched on, frequency variations below 5% are ignored.
