Remote interface operation
APPLy:RAMP [[,[,]]]
(The command generates ramp wave with 100% symmetry)
Or
FUNCtion {RAMP}
FREQuency {︱MINimum︱MAXimum}
VOLTage {︱MINimum︱MAXimum }
VOLTage:OFFSet {︱MINimum︱MAXimum }
FUNCtion:RAMP:SYMMetry {|MINimum|MAXimum}
Notes
• Symmetry value is stored in volatile memory so the default setting
(100%) will be restored after power-off or a remote interface
reset.
• When you change the output function from ramp wave to another,
the previously-set symmetry is remembered and will be resumed
when ramp wave is re-selected.
• The symmetry setting does not apply to the case where ramp
wave is used as the modulating wave for AM, FM, PM, or PWM.
4.4 Noise Waveform
How to generate a noise wave
1. Press the Noise button to select the output function.
2. Refer to Chapter 3 for configuring common parameters such as
amplitude and dc offset voltage for noise wave.
3. Press the Graph button to view all the waveform parameters.
