TRIGGER SOURCE Selection of trigger source.EXT The W-CDMA chip sequence is startedfrom frame 1 by means of the activeslope of an external trigger signal.The polarity, the trigger threshold andthe input resistance of the TRIGIN inputcan be modified in menuDIGITAL MOD - EXT INPUTS.INT A trigger event is manually executed byEXECUTE TRIGGER.IEC/IEEE-bus :SOUR:WCDM:TRIG:SOUR EXTEXT TRIGGERDELAYEXT RETRIGGERINHIBITSetting the number of chips by which an externaltrigger signal is delayed before it starts the W-CDMAchip sequence.This is used for setting the time synchroneitybetween the DUT and other units.IEC/IEEE-bus :SOUR:WCDM:TRIG:DEL 3Setting the number of chips for which a restart isinhibited after a trigger event.With TRIGGER MODE RETRIG selected, each newtrigger signal restarts the W-CDMA chip sequence.This restart can be inhibited for the entered numberof chips.Example:The entry of 82000 chips, for example, causes newtrigger signals to be ignored for the duration of82000 chips after a trigger event.IEC/IEEE-bus :SOUR:WCDM:TRIG:INH 820001125.5555.03 2.159E-9
