User Manual

The shape of AM modulation waveform checked through oscilloscope is shown as following:

b) Frequency Modulation (FM)

In frequency modulation, modulated waveform is usually composed of carrier wave and

modulation wave. Carrier wave frequency will change as the amplitude of modulation wave

changes.

Press Menu → Mod → Type → FM in turn to start the FM function. The device will output

modulated waveform according to the setting of modulation wave and carrier wave.

Carrier Wave Waveform Selection

FM carrier waveform can be: Sine wave, square wave, ramp wave, pulse wave, arbitrary

wave (except DC) and noise (the default is sine wave). After selecting FM modulation,

press Carrier soft key to enter carrier waveform selection interface.
