Symmetry (Ramp Waves)
Applies to ramp waves only. Symmetry represents the fraction of each
cycle that the ramp wave is rising (assuming that the waveform is not
inverted).
• The symmetry is stored in volatile memory; the default value is 100%.
• The symmetry setting is remembered when you change from ramp to
another waveform. When you return to the ramp waveform, the
previous symmetry value is used.
• If you select a ramp waveform as the modulating waveform for AM,
FM, PM, or PWM, the symmetry setting does not apply.
• Front-Panel Operation: After selecting the ramp function, press the
Symmetry softkey. Then press the 100%, 50%, or 0% softkey or press
Symmetry and use the knob or numeric keypad to enter the desired
symmetry. If you use the numeric keypad, press Percent to complete
the entry.
• Remote Interface Operation:
FUNCtion:RAMP:SYMMetry {<percent>|MINimum|MAXimum}
The APPLy command automatically sets the symmetry to 100%.
