Appendix H: List of Beta Commands and Features
Group:
AFG
Syntax:
AFG:MODULation:TYPe {NONe|AM|FM}
AFG:MODULation:TYPe?
Arguments:
NONe - Value set and returned when AFG:RUNMode is not set to MODUlation.
AM - Amplitude Modulation
FM - Frequency Modulation
Examples:
AFG:MODULation:TYPe AM sets the modulation type to Amplitude Modulation.
AFG:RUNMode
Description:
Sets the operating run mode for the AFG.
Conditions:
Beta Command, see conditions of use. Default setting is CONtinuous.
Group:
AFG
Syntax:
AFG:RUNMode {CONtinuou s|MODUlation|BURst}
AFG:RUNMode?
Arguments:
CONtinuous - Continuous run mode.
MODUlation -M
odulation run mode specified by AFG:MODUlation:TYPE
.
BURst - Burst mode. Also sets AFG:TRIGger:MODe to BURst.
Examples:
AFG:RUNMode CONtinuous sets the run mode to continuous output.
An existing AFG waveform can be 100% amplitude modulated with a 10 kHz
square wave using the following sequence of commands:
AFG:RUNMode MODUlation
AFG:MODULation:TYPe AM
AFG:MODULation:AM:WAVeform SQUare
AFG:MODULation:AM:FREQuency 10e3

n:AM:DEPth 100
AFG:OUTPut:STATE 1
The AFG can be configured to burst play the current signal 1 time, with a 1 ms
interval between bursts using the following sequence of commands:
AFG:RUNMode BURst
AFG:TRIGger:COUnt 1
AFG:TRIGger:INTerval 1.0e-3
AFG:OUTPut:STATE 1
AFG:TRIGger (No Query Form)
Description:
ForcesasoftwaretriggeroftheAFG.
Conditions:
Beta Command, see conditions of use.
Group:
AFG
Syntax:
AFG:TRIGger {FORCE}
Arguments:
FORCe (optional) - Force software trigger.
Examples:
AFG:TRIGger FORCe will force the software AFG trigger.
AFG:TRIGger:COUnt
Description:
Sets the trigger count for the AFG.
Conditions:
Beta Command, see conditions of use. Default setting is 0.
Group:
AFG
Syntax:
AFG:TRIGger:COUnt <NR1>
AFG:TRIGger:COUnt?
MDO4000/B/C, MSO/DPO4000B and MDO3000 Series Oscilloscopes Programmer Manual H-7
Appendix H: List of Beta Commands and Features
Arguments:
<NR1> - Trigger
count value from 0 to 1,000,000 with a resolution of 1. The value
of 0 is equivalent to infinite.
Examples:
AFG:TRIGger:COUnt 0 sets the trigger count to infinite.
AFG:TRIGger:DELay
Description:
Sets the trigger interval for the AFG.
Conditions:
Beta Command, see conditions of use. Default setting is 0.0.
Group:
AFG
Syntax:
AFG:TRIGger:DELay <NR3>
AFG:TRIGger:DELay?
Arguments:
<NR3> - Trigger delay value from 0.0 to 85 with a resolution of 0.1E-9.
Examples:
AFG:TRIGger:DELay 0.0 sets the trigger count to 0.0.
AFG:TRIGger:INTerval
Description:
Sets the trigger interval for the AFG.
Conditions:
Beta Command, see conditions of use. Default setting is 1.0E-3.
Group:
AFG
Syntax:
AFG:TRIGger:INTerval <NR3>
AFG:TRIGger:INTerval?
Arguments:
<NR3> - Trigger interval value from 1.0E-3 to 500 with a resolution of 1.0E-6.
Examples:
AFG:TRIGger:INTerval 1.0E-3 sets the trigger count to 1.0E-3.
