SMIQDigital Standard GSM/EDGEEXECUTETRIGGERExecutes a trigger even to start the GSM signal generation.IEC/IEEE-bus command :TRIG:DM:IMMTRIGGER...Opens a window for selecting the trigger source, for configuring the triggeroutput signals and for setting the time delay of an external trigger signal.Fig. 2-197Menu DIGITAL STD - GSM/EDGE_TRIGGER..., SMIQ equipped with Modulation CoderSMIQB20 and Data Generator SMIQB11(TRIGGER...) TRIGGER SOURCE Selection of trigger source.EXT The GSM signal generation is started bythe active slope of an external triggersignal.The polarity, the trigger threshold andthe input resistance of the TRIGIN inputcan be modified in menuDIGITAL MOD - EXT INPUTS.INT A trigger event can be executed byEXECUTE TRIGGER .IEC/IEEE-bus SOUR:GSM:TRIG:SOUR EXT(TRIGGER...)EXT TRIGGERDELAYEXT RETRIGGERINHIBITSetting the number of symbols by which an externaltrigger signal is delayed before it starts the GSMsignal generation.This is used for setting the time synchronizationbetween the SMIQ and the DUT.IEC/IEEE-bus SOUR:GSM:TRIG:DEL 3Setting the number of symbols for which a restart isinhibited after a trigger event.With TRIGGER MODE RETRIG selected, each newtrigger signal restarts the GSM signal generation.This restart can be inhibited for the entered numberof symbols.Example:The entry of 1000 symbols causes new triggersignals to be ignored for the duration of 1000 symbolsafter a trigger eventIEC/IEEE-bus SOUR:GSM:TRIG:INH 10001125.5555.03 2.307E-9
