Ramp
Arbitrary Waveform
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
