To Output an FSK Waveform
Frequency Shift Keying modulation is a modulation technique that shifts the output signal frequency between two frequen-
cies: the carrier frequency and Hop frequency.
Quick Tip
■ The AFG3000 series instruments generate a phase continuous FSK signal.
1. Follow the steps described on page 46
to display the modulation type selec-
tion submenu.
In this example, select FSK as the
modulation type.
2. The FSK parameter setting screen is
displayed.
Select Internal or External as FSK
source.
3. If you select Internal, you can set the
FSK Rate.
If you select External, the FSK Rate is
ignored.
4. Set Hop Frequency.
Carrier waveform frequency shifts to the
Hop frequency with the specified FSK
rate, and then returns to the original
frequency.
