RESETalso ensures a synchronization of the two fading options during 2-channelmode with the correlation switched on.IEC/IEEE-bus command :SOUR:FSIM:SEQ:RESIn the ON state, frequency variations below 5% are ignored. This enables RFhopping faster than 3 ms. IEC/IEEE-bus command:SOUR:FSIM:IGN:RFCH ON1125.5555.03 2.73 E-9
