FM Freq
Set the modulating waveform frequency.
Frequency range: 1 mHz to 20 kHz (internal source).
To Set Frequency Deviation
Press FM Dev to highlight the parameter and use the numeric keyboard or arrow keys and knob
to input the desired value.
• The deviation should be equal to or less than the carrier frequency.
• The sum of the deviation and the carrier frequency should be equal to or less than
maximum frequency of the selected carrier waveform.
PM (Phase Modulation)
The modulated waveform consists of two parts: the carrier and the modulating waveform. In
PM, the phase of the carrier varies with the instantaneous voltage level of the modulating
waveform.
Press Mod → Type → PM; the parameters of PM modulation are shown in Figure 31.
