UTG9000T Series Function Abitrary Waveform Generator
58
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 FSK modulation, the default modulation source is internal. Rotate multifunction knob or
tap ModSrc tab to step through internal or external modulation source in FSK modulation setting
interface.
1) Internal source
When the modulation source is internal, the modulation wave is a square sine with duty ratio
50% (buit-in and can’t adjustable). It can select shift frequency between the carrier wave
frequency and hopping frequency by the frequency settings.
2) External source
When the modulation source is external, rate will be hidden in paramteter list. Use the
external waveform to modulating the carrier wave. The FSK frequency output is controlled by
logical level on the external digital modulation terminal (FSK Trig connector) on the back
panel.For example, output the current carrier frequency when the external input is low;
