Example 15: Generate a PWM Modulation
Waveform
Generate a PWM modulation waveform with 200Hz key frequency. The carrier
is a pulse wave with 5kHz frequency.
Steps:
Set the frequency, amplitude and offset of the carrier wave.
1. Press Waveforms , and choose the Pulse waveform as the carrier wave
2. Press Frequency/Period and choose Frequency which will display in blue
color. Input ‗5‘ from the keyboard and choose the unit ‗kHz‘ to set the
frequency to 5kHz
3. Press Amplitude/HighLevel and choose Amplitude which will display in
blue
color. Input ‗5‘ from the keyboard and choose the unit ‗Vpp‘ to set the
amplitude to 5Vpp.
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.
5. Press PulWidth/DutyCycle and choose PulWidth which will display in blue
color. Input ‗40‘ from the keyboard and choose the unit ‗us‘ to set the
PulWidth to 40us
Set the modulation type PWM and parameters.
1. Press Mod, Please notice that the message shown on the middle left side
of the screen is ‗PWM ‘.
2. Press PWM Freq
, input ‗200‘ from the keyboard and choose the unit ‗Hz‘ to
set the PWM Freq to 200Hz.
3. Press Width Dev
, input ‗20‘ from the keyboard and choose the unit ‗us‘ to
set the width deviation to 20us
When all parameters above are set, the waveform generated is shown in
