Chapter 5 Modulated Waveform Output   RIGOL 
DG4000 User's Guide 
Carrier Waveform  Frequency Range 
Sine  1μHz to 160MHz 
Square  1μHz to 50MHz 
Ramp  1μHz to 4MHz 
Arbitrary Waveform  1μHz to 40MHz 
 
After the carrier waveform is selected, you can press Freq/Period to highlight 
"Freq", and then use the numeric keyboard or direction keys and knob to input the 
desired frequency value. 
 
Modulation Source 
 
4FSK uses internal modulation source and the modulating waveform is Sine. 
 
To Set the 4FSK Rate 
 
4FSK uses internal modulation source. Press KeyFreq to set the frequency at 
which the output frequency shifts between "carrier frequency" and three "hop 
frequencies". 
  Use the numeric keyboard or direction keys and knob to input the desired 
frequency value.  
  The frequency range is from 2mHz to 1MHz and the default is 100Hz. 
 
To Set the Hop Frequencies 
 
Alternating frequencies ("hop" frequencies) are the modulating frequencies. The 
ranges of hop frequencies depend on the carrier waveform currently selected. 
Press HopFreq1, HopFreq2 and HopFreq3 to highlight them and input the 
desire frequency values using the numeric keyboard or direction keys and knob 
respectively. 
  Sine: 1μHz to 160MHz 
  Square: 1μHz to 50MHz 
  Ramp: 1μHz to 4MHz 
  Arb: 1μHz to 40MHz
