SMIQDigital Standard NADC(POWER RAMPCONTROL...)SET DEFAULTResets the subsequent parameters to the factory-setvalues.IEC/IEEE-bus :SOUR:NADC:PRAM:PRESRAMP TIMEInput value for the rise and fall time of the envelopeat the beginning or end of a slot. The time is set inunits of symbol period.IEC/IEEE-bus :SOUR:NADC:PRAM:TIME 0.25RAMP FUNCTIONSelection of shape of rising and falling ramp forenvelope control.LIN Linear ramp function.COS Cosine function. A more favourablespectrum than that of the LIN function isobtained.IEC/IEEE-bus :SOUR:NADC:PRAM:SHAP LINRAMP DELAYInput value for a shift of the envelope characteristicto the modulated signal. A positive value causes adelay of the envelope. The values are set in the unitsof the symbol length.IEC/IEEE-bus SOUR:NADC:PRAM:DEL 0.1RISE OFFSETInput value for a positive or negative offset of therising ramp of the envelope at the beginning of a slot.IEC/IEEE-bus :SOUR:NADC:PRAM:ROFF -1FALL OFFSETInput value for a positive or negative offset of thefalling ramp of the envelope at the end of a slot.IEC/IEEE-bus :SOUR:NADC:PRAM:LOFF 1SLOT ATTENUATIONInput value for the level reduction in dB of all active slots whose SLOT LEVELwas set to ATTEN. Menu SELECT SLOT allows the slots to be determinedwhose level is to be reduced.IEC/IEEE-bus command :SOUR:NADC:SLOT:ATT 40 DB1125.5555.03 2.271 E-9
