• Remote Interface Operation:
FUNCtion:SQUare:DCYCle {<
percent
>|MINimum|MAXimum}
The
APPLy
command automatically sets the duty cycle to 50%.
Symmetry (Ramp Waves)
Applies to ramp waves only. Symmetry represents the amount of time
per cycle that the ramp wave is rising (assuming that the waveform is
not inverted).
• The symmetry is stored in volatile memory; the symmetry is set to
100% (the default) when power has been off or after a remote
interface reset (assuming the Power On state is set to “default”).
• The symmetry setting is remembered when you change from ramp
wave to another function. When you return to the ramp function,
the previous symmetry is used.
• If use select a ramp waveform as the modulating waveform for AM,
FM, or PWM, the symmetry setting does not apply.
• Front-Panel Operation: After selecting the ramp function, press the
Symmetry
softkey. Then use the knob or numeric keypad to enter the
desired symmetry.
• Remote Interface Operation:
FUNCtion:RAMP:SYMMetry {<
percent
>|MINimum|MAXimum}
The
APPLy
command automatically sets the symmetry to 100%.
