UTG9000T Series Function Abitrary Waveform Generator

select unit in FM modulation setting interface. 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 intput external modulating signal frequency range is between
0Hz~50kHz.
Modulated frequency deviation settings
Frequency deviation indicates the frequency deviation changes between in the FM-modulated
wave frequency and the carrier wave frequency. FM deviation range can set from 0uHz to half of
the maximum current carrier wave frequency. The default range is 1kHz. 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.
The frequency deviation must ≤ the carrier wave frequency, if the frequency deviation is
greater than fundamental frequency, the function/arbitrary waveform generator
automatically limits the deviation to the maximum which allowed by the current
fundamental frequency.
The sum of the frequency deviation and the carrier wave frequency must ≤ the maximum
of the current fundamental frequency, if the frequency deviation value is valid, the
function/arbitrary waveform generator automatically limits the deviation to the maximum
which allowed by the current fundamental frequency.
Comprehensive example
In FM modulation mode, set an internal 2kHz square wave as a modulating signal, another sine
wave with freqeuency 10kHz, amplitude 100mVpp as a carrier wave signal , and set the frequency
deviation to 5kHz, the settings steps as following,
1 Turn on FM modulation mode: tap CH1ModulateFM accordingly.
