4.3.7 To output an AM waveform
A modulated waveform consists of a carrier and a modulation waveform. In AM, for example,
you want to output an AM waveform with 80% modulation depth, the carr ier will be 10kHz
and the modulation waveform will be a 10Hz Ramp wave.
1. Select AM
Press 【Modulate】key and then select 〖AM〗softkey by pressing the〖Mod Type〗softkey.
2. To set Carrier frequency
Press 〖Freq〗 softkey under AM Modulation, enter 10 kHz with the numeric keypad or the knob
and arrow keys. Press 〖kHz〗 softkey to finish entering the number if you are using the numeric
keypad.
3. To set the modulation depth
Press the 〖Depth〗softkey and then set the value to 80% using the numeric keypad or the
knob and arrow keys. Press 〖％〗softkey finish entering the number if you are using the
numeric keypad.
4. To set modulating waveform frequency
Press 〖AM Freq〗softkey and then set the value to 10 using the numeric keypad and finally
press〖Hz〗softkey, or set by the knob and arrow keys.
5. To select the modulation waveform shape
Press the 〖Shape〗softkey then press 【Waveform】key to select the shape of modulating
waveform. For this example, select a 〖Ramp〗 softkey. Finally, press 〖Return〗 softkey to back
to AM menu.
