UTG9000T Series Function Abitrary Waveform Generator
Carrier wave frequency settings
Refer to The carrier wave frequency settings of AM modulation.
Hopping frequency settings
Rotate multifunction knob, push direction key or tap HopFreq1 and HopFreq2 tab to pop-out visual numeric
keyboard to enter values and select unit in 3FSK modulation setting interface. The range of hopping frequency
depends on carrier waveform. Refer to Tabe 4-1/4-2 of AM modulation.
Modulation waveform frequency settings
When the modulation source is internal, it can select shift frequency between the carrier wave frequency and
hopping frequency. Turn on 3FSK modulation mode to set the frequency, the range is between 1μHz~2MHz, default
100Hz. Rotate multifunction knob, push direction key or tap ModFreq tab to pop-out visual numeric keyboard to enter
values and select unit in modulation setting interface.
Comperhensive example
In FSK modulation mode, set an internal 2kHz,1Vpp sine wave as a carrier wave, set HopFreq1 to 1kHz, set
HopFreq2 to 5kHz, make the carrier wave and hopping frequence shift between within 100Hz frequency. The
settings steps as following,
1) Turn on FSK modulation mode: tap CH1→Modulate→3FSK accordingly.
