Enter the duty cycle in the [Duty Start] and [Duty End] entry boxes. The display changes
so that values can be entered only when the output waveform is set to pulse wave. The
[Duty End] entry box is set only when sweeping the duty cycle. The range is 0 to 100%.
The resolution is 0.1%. The default is 50%.
Note
When the output waveform is pulse, the waveform may not be output if "(1/output frequency) x
duty cycle setting < 10 µs." For output frequency settings, see the next section.
Enter the output frequency in the [Freq Start] and [Freq End] entry boxes. [Freq End] is
set only when sweeping the frequency. For the selectable range and resolution, see
section 5.1, "Performance Specifications." When the output waveform is a sine wave, the
frequency can be set in the range from 1 mHz to 20 kHz. For all other waveforms, the
frequency can be set in the range from 1 mHz to 10 kHz. The default is 1 kHz.
Enter the amplitude of the output voltage in the [Ampl Start] and [Ampl End] entry boxes.
[Ampl End] is set only when sweeping the voltage. For the selectable range and
resolution, see section 5.1, "Performance Specifications." When the output waveform is
set to DC, the output voltage is set to the offset voltage as described in the next section.
The default amplitude is 2 Vp-p.
Enter the offset value of the output voltage in the [Offset] entry box. The range is
confined to the output range. For the resolution, see section 5.1, "Performance
Specifications." The default is 0 V. When the output waveform is set to DC, this offset
value is the output voltage.
Set the phase of the output waveform for each channel. Enter the initial phase at the
start of the oscillation in the [Phase] entry box. The range is 0 to +360 deg regardless of
the type of output waveform. The resolution is 0.1 deg. The default is 0 deg.
Note
The phase difference of the waveforms between channels will not necessarily be that which you
specified between the channels. In addition, when the output waveform is set to a waveform other
than pulse, the skew between the channels become large as the output frequency is lowered.
