AFG3000 Series Quick Start User Manual

Frequency Shift Keying modulation is a modulation technique that shifts the output signal frequency between two frequen-
cies: the carrier frequency and Hop frequency.

■

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.
