Chapter 5 Modulated Waveform Output RIGOL
DG4000 User's Guide
5-27
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
3FSK uses internal modulation source and the modulating waveform is Sine.
To Set the 3FSK Rate
3FSK uses internal modulation source. Press
KeyFreq to set the frequency at
which the output frequency shifts between "carrier frequency" and the two "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 and HopFreq2 to highlight them and input the desire frequency
values using the numeric keyboard or direction keys and knob respectively.
