3.12 Example 12: Generating a FSK Modulation
Waveform
Generate a FSK modulation waveform with 200 Hz key frequency. The carrier
is a sine wave with 10 kHz frequency, and the hop frequency is 500 Hz. Follow
these 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 a
blue color. Input
‟10‟ from the keyboard and choose the unit „kHz‟ to set the
frequency to 10 kHz.
3. Press Amplitude/HighLevel and choose Amplitude which will display in a
blue color. Input
‟5‟ from the keyboard and choose the unit „Vpp‟ to set the
amplitude to 5 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
Vdc.

Set the modulation type FSK and parameters.
1. Press Mod
→ Type → FSK, choose FSK. Please notice that the message
shown on the middle left side of the screen is „FSK‟.
2. Press Key Freq, input
‟200‟ from the keyboard and choose the unit „Hz‟ to
set the key frequency to 200 Hz.
3. Press Hop Freq
, input „500‟ from the keyboard and choose the unit „Hz‟ to
set the hop frequency to 500 Hz.
When all parameters above are set, the waveform generated is shown in
Figure 3-12.
