UTG9000T Series Function Abitrary Waveform Generator
Carrier wave frequency settings
Refer to The carrier wave frequency settings of AM modulation.
Select the trigger source of modulation
UTG9000T function/arbitrary waveform generator can select internal or external of the modulation trigger source. When turn
on OSK modulation, the default modulation source is internal. Rotate multifunction knob or tap TrigSrc tab to step through
internal or external modulation source in OSK modulation setting interface.
1） Internal trigger source
When the modulation source is internal, the modulation wave is sine wave. Use OSK rate to control the
phase relationship of oscillation starting and stopped.
2） External trigger source
When the modulation source is external, rate will be hidden in paramteter list. Use the external waveform to
modulating the carrier wave. The OSK phase output is controlled by logical level on the external digital
modulation terminal (FSK Trig connector) on the back panel.For example, output the current oscillation
wave when the external input is low; stop output when the external input is high.
