Select the source of modulation
UTG9000T function/arbitrary waveform generator can select internal or external modulation source. When turn on SUM
modulation, the default modulation source is internal. Rotate multifunction knob or tap ModSrc tab to step through internal
or external modulation source in SUM modulation setting interface.

1）Internal source
UTG9000T function/arbitrary waveform generator can select internal or external modulation source. When turn on SUM
modulation, the default modulation source is internal. Rotate multifunction knob or tap ModSrc tab to step through internal
or external modulation source in AM 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
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 SUM modulation depth is controlled by the ±5V signal
level on the external analog modulation input terminal (Modulation In connector) on the back panel. For example, if
set the modulation depth to 100%, the output of SUM amplitude is maximum when the external modulation signal is
+5V; the output of SUM amplitude is minimum when the external modulation signal is -5V.
