SOURce:NADC SubsystemSMIQ[:SOURce]:NADC:TRIGgerOUTPut[2]:DELay 0 to 971The command determines the delay of the signal at trigger output 2 in comparison with the start ofthe frames/slots in number of symbols.Example: :SOUR:NADC:TRIG:OUTP2:DEL 16 *RST value is 0[:SOURce]:NADC:TRIGger:OUTPut[2]:PERiod 1 to 67.1E6The command sets the repeat rate (in number of frames) of the signal at trigger output 2.Example: :SOUR:NADC:TRIG:OUTP2:PER 8 *RST value is 1[:SOURce]:NADC:CLOCkThe commands for setting the data clock are under this node.[:SOURce]:NADC:CLOCk:SOURce INTernal | EXTernalThe command selects the source for the DM data clock.INTernal The internal clock generator is used and output via the clock outputs of the serial andparallel interface.EXTernal The clock is externally fed in via the serial interface and output via the parallelinterface.Example: :SOUR:NADC:CLOC:SOUR INT *RST value is INT[:SOURce]:NADC:CLOCk:MODE BIT | SYMBolThe command sets the clock mode for :NADC:CLOCk:SOURce EXTernal.BIT The external clock has to be a bit clock.SYMBol The external clock has to be a symbol clock.The bit and symbol clock only differ for this modulation, because it has more than two states, i.e.more than one bit is required to code each state.Example: :SOUR:NADC:CLOC:MODE BIT *RST value is SYMB[:SOURce]:NADC:CLOCk:DELay 0 to 1.0The command sets the delay of the symbol clock (as a fraction of the length of a symbol).Example: :SOUR:NADC:CLOC:DEL 0.75 *RST value is 0[:SOURce]:NADC:PRAMpThe commands for the level control of the burst are under this node.[:SOURce]:NADC:PRAMp:PRESetThis command sets the standard-stipulated values for the following commands of level control. Itis an event and hence has no query and no *RST value.Example: :SOUR:NADC:PRAM:PRES[:SOURce]:NADC:PRAMp:TIME 0.25 to 16.0The command sets the cutoff steepness (in symbol clocks).Example: :SOUR:NADC:PRAM:TIME 2.5 *RST value is 3[:SOURce]:NADC:PRAMp:DELay -1.0 to + 1.0The command defines the shift of the envelope characteristic to the modulated signal. A positivevalue causes a delay of the envelope.1125.5555.03 3.118E-9
