Set initial phase
1. Press
→
phase to set parameter value of initial phase.
The displayed initial phase is either the power-on default value or the phase previously selected.
Use the current value if the phase is valid for the new waveform when changing parameters.
2. Enter the desired amplitude
Use numeric keypad or knobs to enter the desired value and then select the unit.

2.1.2 Square wave setup
Press
and the operation menu of square wave will be displayed at the bottom of the
screen. Use operation menu of square wave to set its output waveform parameters.
Major parameters of square wave include frequency/cycle, amplitude/high level, offset/low level,
duty cycle and phase. Different square waves are obtained by altering these parameters. As shown
in Figure 2-6, select
duty cycle
in the menu of softkey and the parameter value corresponding to
duty cycle will be selected in the parameter display area, in which users could alter the value of
duty cycle of square wave.
