1) Internal source
When the modulation source is internal, the modulation waveform can be sine, square, rising
ramp, falling ramp arbitrary and noise wave. The default wave is sine wave. When turn on FM
modulation, ModWave present Sine, rotate multifunction knob or tap word Sine to select the
waveform in modulation setting interface.

Square wave: duty ratio 50%

Rising ramp wave: symmetry 100%

Falling ramp wave: symmetry 0%

Arbitrary wave: the length of arbitrary wave limit at 2kpts by the method of select point
automatically

Noise wave: white gaussian noise
2) External source
When the modulation source is external, the modulation wave and frequence will be hidden in
parameter list. Use the external waveform to modulating the carrier wave. The FM offset is
controlled by the ±5V signal level on the external analog modulation input terminal (Modulation In
connector) on the back panel. The frequency of the output at the positive signal level is greater
than the carrier wave frequency, at the negative signal level is less than the carrier wave
frequency, the lower external signal level produces less deviation. For example, if set the
frequency deviation to 1kHz, the FM output increased by 1kHz to the current fundamental
frequency when the external modulated signal is +5V; the FM output subtracted by 1kHz from the
current fundamental frequency when the external modulated signal is -5V.
Modulation waveform frequency settings
When the modulation source is internal, it can set the modulation waveform frequency, and the
frequency range is between 1uHz~2MHz, the default range is 100Hz.
