Example 16: Generate a DSB-AM Modulated Waveform
Generate a DSB-AM modulated waveform with 100 Hz modulating frequency. The carrier is a
sine wave with 2 kHz frequency.
⚫ 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 a blue color. Input ‘2’
from the keyboard and choose the unit ‘kHz’ to set the frequency to 2 kHz
3. Press Amplitude/HighLevel and choose Amplitude which will display in a blue color. Input
‘4’ from the keyboard and choose the unit ‘Vpp’ to set the amplitude to 4 Vpp.
4. Press Offset/LowLevel and choose Offset which will display in a blue color. Input ‘0’ from
the keyboard and choose the unit ‘Vdc’ to set the offset to 0 V DC.
⚫ Set the modulation type DSB-AM and its parameters.
1. Press Mod → Type → DSB-AM and choose DSB-AM. 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 100 Hz.
When all parameters above are set, the waveform generated is shown in Figure 89.
