DM General Remote-Control Commands The following section contains the commands for generating the digital modulation signal.
® Remote Control Commands R&S SMU200A SOURce Subsystem Parameters: <Length> 9|11|15|16|20|21|23 *RST: Example: BB:DM:SOUR PRBS The internal pseudo-random generator is used as the data source. BB:DM:PRBS 9 An internal pseudo-random sequence of 511 bits will be gener- ated. [:SOURce<hw>]:BB:DM:PRESet The command calls the default settings for digital modulation.
® Remote Control Commands R&S SMU200A SOURce Subsystem Example: BB:DM:SOUR DLIS the internal data generator is used. BB:DM:DLIS:SEL 'test' the data list test.dm_iqd is used. [:SOURce<hw>]:BB:DM:SRATe <Srate> The command sets the symbol rate. The value range is dependent on the selected mod- ulation type.
® Remote Control Commands R&S SMU200A SOURce Subsystem [:SOURce<hw>]:BB:DM:STATe <State> The command enables or disables digital modulation. Switching on digital modulation turns off all the other digital standards. Enabling digital modulation (BB:DM:STAT ON) turns off all the other standards. In case of two-path instruments, this affects the same path.
Page 645
® Remote Control Commands R&S SMU200A SOURce Subsystem [:SOURce<hw>]:BB:DM:CLOCk:MODE <Mode> The command enters the type of externally supplied clock (:BB:DM:CLOCk:SOURce EXTernal). The bit clock and the symbol clock differ only in the case of modulations that have more than two states, i.e. that require more than one bit for encoding each state. When MSYMbol is used, a multiple of the symbol clock is supplied via the CLOCK connector and the symbol clock is derived internally from this.
® Remote Control Commands R&S SMU200A SOURce Subsystem [:SOURce<hw>]:BB:DM:CLOCk:SOURce <Source> The command selects the source for the digital modulation clock. For two-path instruments, selecting COUPLed and EXTernal is only possible for path A, since the external clock source is permanently allocated to path A; clock source AINT is only allowed for path B.

® Remote Control Commands R&S SMU200A SOURce Subsystem Example: BB:DM:TRIG:SOUR INT sets internal triggering. BB:DM:TRIG:SEQ ARET sets Armed_Retrigger mode, i.e. every trigger event causes signal generation to restart. BB:DM:TRIG:EXEC executes a trigger, signal generation is started. BB:DM:TRIG:ARM:EXEC signal generation is stopped.
Page 648
® Remote Control Commands R&S SMU200A SOURce Subsystem Parameters: <Output> 0|1|OFF|ON The signal calculation starts simultaneously with the external trigger event but because of the instrument’s processing time the first samples are cut off and no signal is outputted. After elapsing of the internal processing time, the output signal is synchronous to the trigger event.
