frequency range is between 1uHz~2MHz, the default range is 100Hz. Rotate multifunction knob,
push direction key or tap ModFreq tab to pop-out visual numeric keyboard to enter values and
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.
Duty ratio deviation settings
Duty ratio deviation is deviation of modulated waveform from the current carrier duty ratio. The
range of PWM can set to 0%
~49.999825%, the default is 49.999825%. Rotate multifunction knob,
push direction key or tap DutyDev tab to pop-out visual numeric keyboard to enter values and
select unit in FM modulation setting interface.
 Duty ratio deviation is deviation of modulated waveform from the current carrier duty ratio
(express by %).
 Duty ratio deviation can’t exceed the duty ratio of the current pulse wave.
 The sum of duty ratio deviation and the current pulse wave must be ≤99.99%
 The minimum duty ratio of pulse wave and the currenr edge time will effect the duty ratio
settings.
Comperhensive example
In PWM modulation mode, set an internal 1kHz sine wave as a modulating signal, another pulse
wave with freqeuency 10kHz, amplitude 2Vpp，duty ratio 50%, rising/falling edge time 100ns as a
carrier wave signal , and set the frequencyduty ratio deviation to 40%, the settings steps as
following,
1） Turn on FM modulation mode: tap CH1→Modulate→FM accordingly.
