See Carrier Frequency Wave Setting
The frequency range of pulse wave is 1μH~30MHz. Default frequency is 1kHz. To set carrier
frequency, please use multi-functional knob and direction key in the interface or press soft function
key Param →
Freq and input the required value and select the unit.
Set carrier duty ratio
The range of duty ratio of pulse wave is 0.01%~99.99%. Default duty ratio is 50%. To set carrier duty
ratio, please use multi-functional knob and direction key in the interface or press soft function key
Param →
Duty , input the required value and select the unit.
Select modulation source
UTG2000B function/arbitrary waveform generator can select internal or external modulation source.
After you use PWM function, you can see that modulation source is internal by default. You can
change it with multi-functional knob on the interface for using frequency modulation
function or by pressing Param → Source →
External
