3.16 Example 16: Generate a DSB-AM Modulation
Waveform
Generate a DSB-AM modulation waveform with 100Hz modulating frequency.
The carrier is a sine wave with 2kHz frequency.
 Steps:
 Set the frequency, amplitude and offset of the carrier wave.
1. Press Waveforms, and choose the sine waveform as the carrier wave.
2. Press Frequency/Period and choose Frequency which will display in blue
color. Input ‘2’ from the keyboard and choose the unit ‘kHz’ to set the
frequency to 2kHz
3. Press Amplitude/HighLevel and choose Amplitude which will display in
blue color. Input ‘4’ from the keyboard and choose the unit ‘Vpp’ to set the
amplitude to 4Vpp.
4. Press Offset/LowLevel and choose Offset which will display in blue color.
Input ‘0’ from the keyboard and choose the unit ‘Vdc’ to set the offset to
0Vdc.
 Set the modulation type DSB-AM and parameters.
1. Press Mod → Type → DSB-AM, choose DSB-AM. Please notice that the
message shown on the middle left side of the screen is ‘DSB-AM ’.
2. Press DSB Freq, input ‘100’ from the keyboard and choose the unit ‘Hz’ to
set the DSB Freq to 100Hz.
When all parameters above are set, the waveform generated is shown in
Figure 3-16.
