2 Features and Functions
Symmetry (Ramp Wave)
This configuration applies to Ramp wave only. Symmetry
represents the amount of time per cycle that the Ramp wave
is rising (assuming that the waveform is not inverted).

• The symmetry percentage is stored in volatile memory
where the symmetry is set to default 100% upon power-off
or after a remote interface reset.
• The symmetry setting is stored when you change from
Ramp wave to another function. Thus, when you return to
the Ramp function, the previous symmetry is used.
• If you select a Ramp waveform as the modulating
waveform for AM, FM, or PM, the symmetry setting does
not apply.
Soft Front Panel Operation
After selecting Ramp at the top panel as shown in
Figure 2-2, on the Symmetry panel below, input the desired
symmetry value.
