[:SOURce]:FUNCtion[1|2]:RAMP:SYMMetry[?]
Set the symmetry percentage for ramp waves. Symmetry represents the
amount of time per cycle that the ramp wave is rising (assuming that the
waveform polarity is not inverted). You can set the symmetry to any value
from 0% to 100%. The default is 100%. MIN = 0%. MAX = 100%. The
:SYMM? query returns the current symmetry setting in percent.
For ramp waveforms, the APPLy command overrides the current symmetry
setting and automatically selects 100%.
The symmetry setting is remembered when you change from ramp wave to
another function. When you return to the ramp wave function, the previous
symmetry is used. If you select a ramp waveform as the modulating
waveform for AM or FM, the symmetry setting does not apply.
