3.12. Example 12:Generate a FSK Wave
Generate a FSK waveform with 200Hz key frequency. The carrier is a sine
wave with 10kHz frequency, and the hop frequency is 500Hz.
Steps:
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’5’
from the keyboard and choose the unit ‘Vpp’ to set the amplitude 5Vpp.
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.
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 200 Hz.
3. Press Hop Freq, input ‘500’ from the keyboard and choose the unit ‘Hz’ to
set the hop frequency 500Hz.
When all parameters above are set, the wave generated is shown in Figure
3- 12:
