3.10. Example 10:Generate a FM Wave
Generate a FM waveform, the carrier is a sine wave with 10kHz frequency,
and the modulating wave is a sine wave with 1 Hz frequency, 2kHz frequency
deviation.
¾
Steps:
z
Set the frequency, amplitude and offset of the carrier wave.
1. Press Sine and choose the sine waveform as the carrier wave
2. Press Freq and choose Freq which will display in white color. Input’10’
from the keyboard and choose the unit ‘kHz’ to set the frequency 10kHz
3. Press Ampl and choose Ampl which will display in white color. Input’1’
from the keyboard and choose the unit ‘Vpp’ to set the amplitude 1Vpp.
4. Press Offset and choose Offset which will display in white color. Input’0’
from the keyboard and choose the unit ‘Vdc’ to set the offset 0Vdc.
z
Set the modulation type FM and parameters.
1. Press Mod

FM, choose FM. Please notice that the message
shown on the middle left side of the screen is ‘FM’.
2. Press FM Freq, input ‘1’ from the keyboard and choose the unit ‘Hz’ to set
the AM Freq 1Hz.
3. Press FM Dev, input ‘2’ from the keyboard and choose the unit ‘kHz’ to
set the FM deviation 2kHz.
4. Press
