Waveform and the Carrier Waveform ranging from 0° to 180°. 

 

FSK (Frequency Shift Keying) 

The FSK Modulation is a modulation method, the output frequency of which switches 
between two the pre-set frequencies (Carrier Waveform Frequency and the Hop 
Frequency). The Frequency of the Output Frequency switch between the carrier waveform 
frequency and the Hop frequency is called the 

FSK rate

. The frequency by which the 

output frequency switch from each other is determined by the Internal Frequency 
generator or the Signal Voltage Level offered by the 

Ext Trig/FSK/Burst

 connector in the 

rear panel. The Carrier Waveform can only be Sine. The user interface of the FSK is 
shown as below.

How to set the parameters of FSK 

(1) 

Press 

Mod

 function button to enter the Modulation mode.   

(2) 

Press 

 F1 

  to switch Mod Type to FSK. If the Carrier Waveform is not Sine, the 

system will switch it to Sine automatically.   

(3) 

Press 

 button to display the waveform and parameters of the Carrier 

Waveform. You can change the parameters, please refer to "

To Output Sine Signals

" 

on P11. Press 

  button again to return to the Modulation mode interface.   

(4) 

Press 

 F5 

 to select the source. If the source is External, use the 

Ext 

Trig/FSK/Burst 

connector in the rear panel to input the external signal, then skip 

ahead to step (5). If you choose Internal, continue to the steps below.   

(5) 

Press 

 F3 

  to set FSK Rate. The range is 1

μ

Hz

～

100KHz (Internal source only).   

(6) 

Press 

 F4 

  to set Hop Frequency. The range is 1
