Figure 2-7 Setup Parameter Value of Duty Cycle
2.1.3 Set ramp wave
Press
and the operation menu of ramp wave will be displayed at the bottom of the
screen. Use operation menu of ramp wave to set its output waveform parameters.
Major parameters of ramp wave include frequency/cycle, amplitude/high level, offset/low level,
symmetry and phase. Different ramp waves are obtained by altering these parameters. As shown in
Figure 2-8, select Symmetry in the menu of softkey and the parameter value corresponding to
symmetry will be selected in the parameter display area, in which users could alter the value of
symmetry of ramp wave.
