8. FUNCtion:RAMP:SYMMetry?
Command
Format
FUNCtion:RAMP:SYMMetry? [MINimum|MAXimum]
Function
Query the symmetry of ramp wave from CH1.
Return
Value
The query returns current symmetry settings with the format of
percent, such as 50.000000.
9. FUNCtion:CH2
Command
Format
FUNCtion:CH2 {SINusoid|SQUare|RAMP|PULSe|NOISe|DC|USER}
Function
Select the output function form CH2.
Explanations
If send FUNC:CH2 DC and then FUNC:CH2 USER, the output is
still DC.
Example
FUNC:CH2 SIN
10. FUNCtion:CH2?
Command
Format
FUNCtion:CH2?
Function
Query the output function from CH2.
Explanations
The query always returns CH2:ARB after sending FUNC:CH2 DC or
FUNC:CH2 USER.
Example
The query returns CH2:SIN, CH2:SQU, CH2:RAMP, CH2:PULS,
CH2:NOIS or CH2:ARB, the default is CH2:SIN.
11. FUNCtion:USER:CH2
Command
Format
FUNCtion:USER:CH2 {< name of arbitrary wave >|VOLATILE}
Function
Separately select any one wave from built-in arbitrary waves and 10
user-defined waves for CH2 or select the wave that has been
loaded into volatile memory.
Explanations
 The built-in waves contains:
