[:SOURce[]][:MOD]:FM:INTernal:FUNCtion
Syntax [:SOURce[]][:MOD]:FM:INTernal:FUNCtion
[:SOURce[]][:MOD]:FM:INTernal:FUNCtion?
Description Set the FM modulation waveform of the specified channel.
Query the FM modulation waveform of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Discrete
SINusoid|SQUare|TRIangle|
RAMP|NRAMp|NOISe|USER
SINusoid
Explanation  This command is only applicable to the internal modulation source
( [:SOURce[]][:MOD]:FM:SOURce ).
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
 SQUare: 50％ duty cycle; TRIangle: 50％ symmetry; RAMP: 100％
symmetry; NRAMp: 0％ symmetry; USER: the arbitrary waveform selected of
the specified channel.
Return Format The query returns SIN, SQU, TRI, RAMP, NRAMP, NOIS or USER.
Example :SOUR1:FM:INT:FUNC SQU /*Set the FM modulation waveform of CH1 to
square*/
:SOUR1:FM:INT:FUNC? /*Query the FM modulation waveform of CH1 and
the query returns SQU*/
