Digital Standard W-CDMA (NTT DoCoMo/ARIB 0.0)SMIQ(MODULATION...) FILTER MODE Selection of filter mode.LOW_ACP Filter for minimum Adjacent ChannelPower.IEC/IEEE-bus command:SOUR:WCDM:FILT:MODE LACPLOW_EVM Filter for minimum vector error.IEC/IEEE-bus command:SOUR:WCDM:FILT:MODE LEVMLOW DISTORTIONMODESwitch on/off of low-distortion mode.After switch-on, the level of the IQ baseband signalsis reduced by 3 dB. In some cases, this might reduceundesired intermodulation products. OFF is normallythe more favourable setting.IEC/IEEE-bus :SOUR:WCDM:LDIS:STAT OFFTRIGGER MODEEXECUTE TRIGGERTRIGGER...Opens a window for selecting the W-CDMA sequence.AUTOThe calculated W-CDMA chip sequence is cyclicallyrepeated.IEC/IEEE-bus command :SOUR:WCDM:SEQ AUTORETRIGThe W-CDMA chip sequence is continuously repeated.A trigger event causes a restart from frame 1.IEC/IEEE-bus command :SOUR:WCDM:SEQ RETRARMED_AUTO The W-CDMA chip sequence cannot be started fromframe 1 until a trigger event has occurred. The unitthen automatically switches over to the AUTO modeand can no longer be triggered.IEC/IEEE-bus command :SOUR:WCDM:SEQ AAUTARMED_RETRIG The W-CDMA chip sequence cannot be started fromframe 1 until a trigger event has occurred. each newtrigger event causes a restart.IEC/IEEE-bus command :SOUR:WCDM:SEQ ARETExecutes a trigger event to start the W-CDMA chip sequence.IEC/IEEE-bus command :TRIG:DM:IMMOpens a window for selecting the trigger source, for configuring the triggeroutput signals and for setting the time delay of an external trigger signal.1125.5555.03 2.158E-9
