[:SOURce[<n>]]:FUNCtion:RAMP:SYMMetry 
[:SOURce[<n>]]:FUNCtion:RAMP:SYMMetry <val> 
[:SOURce[<n>]]:FUNCtion:RAMP:SYMMetry? 
Set or query the ramp symmetry (the percentage that the rising period takes up in the 
whole period) of the specified source channel.   
If omitted, the operation is 
performed on source 1 by 
default 
The query returns the symmetry in scientific notation, such as 5.000000e+01.   
:FUNCtion:RAMP:SYMMetry 50 /*Set the ramp symmetry of source 1 to 50%*/ 
:FUNCtion:RAMP:SYMMetry?            /*The query returns 5.000000e+01*/ 
[:SOURce[<n>]]:FUNCtion[:SHAPe] 
 
 
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude] 
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude] <Amplitude> 
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]? 
Set or query the output amplitude of the specified source channel. The default unit is Vpp.   
If omitted, the operation is 
performed on source 1 by 
default 
Related to the output 
impedance   
HighZ: 20mVpp to 5Vpp 
50Ω: 10mVpp to 2.5Vpp 
You can use the [:SOURce[<n>]]:OUTPut[<n>]:IMPedance command to set the output 
impedance. 
The query returns the amplitude in scientific notation, such as 1.0000000e+00.   
:VOLTage 2 /*Set the output amplitude of source 1 to 2V*/ 
:VOLTage?          /*The query returns 2.0000000e+00*/
