[:SOURce[]]:FUNCtion:RAMP:SYMMetry
Syntax [:SOURce[]]:FUNCtion:RAMP:SYMMetry {|MINimum|MAXimum}
[:SOURce[]]:FUNCtion:RAMP:SYMMetry? [MINimum|MAXimum]
Description Set the ramp symmetry of the specified channel.
Query the ramp symmetry of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Real 0% to 100% 50%
Explanation  The symmetry is defined as the percentage that the rising period of the ramp
waveform takes up in the period.
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the symmetry in scientific notation with 7 effective digits, for
example, 5.500000E+01 (the ramp symmetry is 55%).
Example :SOUR1:FUNC:RAMP:SYMM 55 /*Set the ramp symmetry of CH1 to 55%*/
:SOUR1:FUNC:RAMP:SYMM? /*Query the ramp symmetry of CH1 and the query
returns 5.500000E+01*/
