To Output DC
(1) Press CH1/2 to select the channel that you want to output DC.
(2) Press button, then press F4 to enter the Built-in Wform menu.
(3) Press F4 to select Others. Select DC. Press F1 to output DC.
(4) Press F3 , confirm whether the "Offset" menu item is highlighted; if not, press
F3 to switch into "Offset". In Parameter 3, a cursor appears under the value of
offset. Use the knob or the number keys to set the desired value and choose the unit.

To Generate the Modulated Waveform
Modulation function is only used for CH1. Press the Mod button, then press F1 to
select Mod to generate modulated waveform. The waveform generator can modulate
waveform using AM, FM, PM, PWM, FSK, ASK and PSK. To turn off the modulation, press
the Mod button.
AM (Amplitude Modulation)
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. The Carrier Waveform can only be Sine. In AM, the amplitude of
the Carrier Waveform varies with the instantaneous voltage of the modulating waveform.
The user interface of the AM is shown as below.
