Frequency modulation, namely the frequency of the carrier waveform varies with the
amplitude of the modulating waveform, as shown in the figure below.
Figure 12-9 Frequency Modulation
1. Select the carrier waveform
Press Src1Conf to enter the waveform setting interface. Press Wave to select
the desired carrier waveform.
Note: “Pulse”, “DC” and “Noise” cannot be selected.
2. Set the carrier waveform parameters
After selecting the desired carrier waveform, set the carrier parameters (such as
the frequency and amplitude) by referring to the corresponding introductions
above.
3. Select the modulating waveform
Press Src1Mod to open the Source1 modulation setting menu. Press Shape to
select the desired modulating waveform (sine, square, ramp or noise).
4. Set the modulation frequency
Press Frequency to set the frequency of the modulating waveform. The range
is from 1 Hz to 50 kHz.
