To Generate the Modulated Waveform 

 
Use the Mod button to generate modulated waveform. DG2000 Series can generate 
AM, FM, FSK, PM or PWM modulated waveforms. The modulation parameters should 
be set in different types of modulation. For example, in AM, users can set the Source 
(Internal/ External), depth, Modulating Frequency, Modulating Waveform and Carrier 
Waveform; in FM, users can set the Source (Internal/ External), Frequency Deviation, 
Modulating Waveform and Carrier Waveform; in FSK, users can set the Source 
(Internal/ External), Hop Frequency, FSK Rate, Modulating Waveform and Carrier 
Waveform; while in PM, users can set the Source (Internal/ External), Phase Deviation, 
Modulating Frequency, Modulating Waveform and Carrier Waveform, etc. 
 
We will explain how to set these parameters in details according to different types of 
Modulation.
