Carrier wave frequency settings
Refer to The carrier wave frequency settings of AM modulation.
Select the source of modulation
UTG9000T function/arbitrary waveform generator can select internal or external modulation source. When turn on FM
modulation, the default modulation source is internal. Rotate multifunction knob or tap ModSrc tab to step through internal
or external modulation source in PM modulation setting interface.
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. Whturn 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

 Noise wave: white gaussian noise
2) External source
