[:SOURce[<n>]]:SUM:INTernal:FUNCtion
Syntax
[:SOURce[<n>]]:SUM:INTernal:FUNCtion {SIN|SQU|RAMP|NOISe|ARB}
[:SOURce[<n>]]:SUM:INTernal:FUNCtion?
Description
Sets the sum source of the waveform combine function of the specified channel.
Queries the sum source of the waveform combine function of the specified channel.

{SIN|SQU|RAMP|NOISe|ARB}
Discrete
SIN|SQU|RAMP|NOISe|ARB
SIN
Remarks
 The sum source refers to the waveform to be summed on the basic waveform, and it can be Sine (SIN),
Square (SQU), Ramp (RAMP), Noise (NOISe), or Arbitrary waveform (ARB).
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns SIN, SQU, RAMP, NOISE, or ARB.
Example
:SOUR1:SUM:INT:FUNC SQU /*Sets the sum source of the waveform combine function of CH1 to Square.*/
:SOUR1:SUM:INT:FUNC? /*Queries the sum source of the waveform combine function of CH1 and the
query returns SQU.*/
[:SOURce[<n>]]:SUM[:STATe]
Syntax
[:SOURce[<n>]]:SUM[:STATe] {ON|1|OFF|0}
[:SOURce[<n>]]:SUM[:STATe]?
Description
Enables or disables the waveform combine function of the specified channel.
Queries the on/off status of the waveform combine function of the specified channel.

OFF
Remarks
 Waveform combine refers to combining the specified waveform with the basic waveform, and then
output the combined waveform. This function is only applicable to the basic waveforms.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns ON or OFF.
Example
:SOUR1:SUM ON /*Enables the waveform combine function of CH1.*/
:SOUR1:SUM? /*Queries the on/off status of the waveform combine function of CH1 and the query
returns ON.*/
